(57) Abstract:

The invention relates to the production of polymeric products. Method of manufacturing polymer product of the polyolefin resin is in its processing with the use of plasticizing monomer system, which is essentially depolymerizing the molded product and which acts as a plasticizer, although it is essentially subsequently polymerized so as to form a product that essentially does not contain a liquid plasticizer. The technical challenge is to develop ways to dramatically increase recycling of polyolefins without significant risk to the physical properties of the final product. 2 C. and 32 C.p. f-crystals.

The invention relates to the production of polymeric products.

Many plastic products are produced by molding the feedstock of the polymer material in the desired shape or configuration by well known processes such as, for example, extrusion, molding sheet smearing or hot calendering in the case of the production of plastic sheets. This requires that the polymer material was essentially a liquid, especially in the case of material with the in order to avoid its decomposition or deterioration of its physical properties.

In the case of polyvinyl chloride (PVC) and similar polymers are more or less extensive use of a technique referred to as vinyl plastisol, when small particles of PVC powder suspended in a liquid carrier in order to reduce its (PVC) viscosity up to a sufficient level where the physical manipulation of them, or by coating the anointing, or by hot calendering or similar process would be possible at an acceptable practice conditions and that on subsequent heating of the mixture of polymer resin PVC melted into an amorphous mass, in which the absorbed carrier liquid. This technology, however, pertains only to the vinyl polymers and cannot be extended to other polymers.

This technology is described in the literature, for example, on page 1385, 1386 Handbook "Handbook of Plastic Materials and Technology" Ed. by Irwin I Ruban, ed. 1990

In practice, however, you may experience significant problems to the environment caused by the migration of liquid plasticizers of the material. The final product may also suffer because of the loss of performance due to the presence of the mod is and when it is used.

A detailed discussion of the problems associated with control loss of liquid plasticizers and related aspects in the field of environment and health, see pages 376-378 guide "Plastic Additives and Modifiers Handbook" Ed. by John Lutz, ed. 1992.

In the case of polyolefins has previously been proposed to introduce a small amount of oils and the like for fine regulation of their ability to recycle. It was also proposed to produce polyolefin products containing more or less large quantities of oil in order to modify the ability to process and receive a specific product characteristics, such as softness. The utility of such products, however, is significantly limited because they contain relatively large quantities of liquid. However, previously it was impossible to significantly extend the capabilities of the processing of polyolefins without significant risk to the physical properties of the final product.

A detailed discussion of the problems associated with plasticizing polyolefins, presented on pages 364 and 365 of the book "Thermoplastic Polymer Additives Theory and Practice" below. editor John Lutz, ed. 1989.

The purpose of this invention is to eliminate or minimize one or more of the specified the ve products from polyolefins and versatility and range of products on the basis of polyolefins can be greatly improved and expanded through the inclusion of a plasticizer or processing AIDS, containing the selectively curable liquid monomer system, which is essentially depolymerizing in the conditions of a molding product, for example by extrusion, coating smearing or celandroni used in the production process of the product (for example, sheet material), although it is essentially polymerized subsequently, so that the formed product is essentially not containing liquid plasticizer. In this regard, it should be understood that typically use initiating substance in order to cause polymerization of the monomer, which is injected into the monomer system with the monomer. Accordingly, in such cases it is important that the initiator was such, that is capable of selectively activated, i.e. is essentially inactive in the conditions of a molding of polyolefin product, but subsequently can be activated under suitable conditions, the polymerization or curing of plasticizing monomer.

Thus, in one aspect this invention relates to a method of manufacturing a plastic product of the polyolefin resin containing the following stages:

- ensuring plasticizing monomer system, which is essentially nepm or celandroni, used in the production process of the product (for example, sheet material), and which acts as a plasticizer or technological additive in the above molding conditions, effectively being subsequently polymerized to obtain a product that essentially does not contain a liquid plasticizer, and plasticizing monomer is contained in an amount of not less than 5 wt. hours at 100 wt.h. polyolefin resins;

- bring at least plasticizing monomer specified plasticizing monomer system in close mixture with the above polyolefin resin (and any additives that may be used with it);

- molding this mixture into the desired product form and subsequent induction of polymerization of the specified plasticizing monomer so as to provide a final product that essentially does not contain liquid plasticizer.

The invention is also applicable to plastic products that are produced by the method of this invention.

To avoid doubt, it should be noted that the term "plasticizing monomer" encompasses a wide range of monomers that can be improved in some way tekuchaya temperature, the monomers, which form a concentrated liquid mixture when they are thoroughly mixed with the polyolefin at ambient temperature, and monomers which, when thoroughly mixed with the polyolefin, are essentially solid at ambient temperature, but is able to form an essentially homogeneous and fluid mixture at elevated temperature, below the temperature of polymerization, and, in particular, under the conditions of the molding product. The expression "plasticizing monomer system" is used here to denote a plasticizing monomer together with any initiator and/or other suitable material, which can be used in the polymerization of plasticizing monomer and which can be put together with the plasticizing monomer at all stages of the method of this invention, or only on (a) its last stage (stages).

In the method of the invention the ability to process the polyolefin in the production of various forms of product from polyolefin substantially improved, thereby expanded the range of possible products that can be made from polyolefins, and achieved significant economic benefits, for example, to increase the political cost, reduce storage requirements molding product, etc. Also offer flexibility with respect to specific forms of polyolefin in the final product can be significantly improved.

Thus, this invention provides advantages both in technology and in the properties of the obtained materials, makes the polyolefins are available for a number of technological methods similar to those used in the field vinylplasts and which was removed earlier, the use of polyolefins. The introduction of different amounts of different types of monomers with a wide range of densities structuring can moreover provide a wide range of physical and chemical properties of the final product. In combination with the ability of this system to include a large amount of fillers and other additives can be obtained from materials ranging from soft elastomers to rigid plastics, from transparent to opaque, from coatings on fabrics to structural materials. The versatility of the systems based on the olefin, thus significantly improved and expanded.

One example of this idea is forming multilayer coatings for floors of metallocene p is receiving.

A number of polyolefins that can be used in accordance with this invention includes polyolefin polymers, copolymers and terpolymer obtained by any known polymerization technology - such as free radical, by means of catalysts of the Ziegler-Natta catalyzed by a single site (metallocene), etc. moreover, such polymers can be used all possible polymer geometric shape such as a linear chain, branched, stereoregular, etc. Hydrocarbon polymer chain may also be replaced in a known manner, for example, the inclusion of functional monomers or by postpolymerization functionalization. Copolymers of olefins and acid monomers (such as Surlyn from Dupont) or polar monomers (such as Enanthene, copolymer ethylene/butyl acrylate from Quantum Chemical) could be examples of such materials. The polymers obtained graft copolymerization in the extruder monomers, such as maleic anhydride with non-functional polyolefins, could also be examples of this. It should be also clear that the polyolefin resin may contain two or more different polyolefins.

Although the way this image is about the only site (metallocene) polyolefins, because of their polymer chains have terminal double bonds and therefore can react with the polymerizable monomer, thereby to some extent the chemical relationship between the polyolefin and the polymerized monomer. This can be useful for improving the physical strength of the material product with improved resistance to the hood and to the pulse shock wave, which tends rather to their absorption due to deformation than to stratification.

A variety of polymeric and polimernye additives can be incorporated in these polyolefin system. They include a number of inorganic fillers and amplifiers, flame retardants, stabilizers, dyes and pigments, and the like. Polymer additives could include modifying additives that increase the impact strength, technological additives, additives that promote compatibility of components, auxiliary additives for mixing, as well as polymer stabilizers, flame retardants, pigments and texturemode supplements. Gas inclusions in the form of a foam with open or closed cells can also be part of a polyolefin system. This is achieved through the use of intumescent chemical substances that t is ω of the present invention to obtain a microporous polyolefin products using Monomeric systems, which can be extracted from a product to a greater or lesser degree, usually using a solvent after polymerization of the monomer. In this case, the monomer system is chosen so that it was essentially monofunctional, in order to avoid essentially the cross-linking monomer and/or a polyolefin, preferably receiving not more than 0.1% stitching. Thus can be obtained a variety of pore sizes, mainly from 20 to 3000 nm, for example from 100 to 1000 nm in diameter. Mostly smaller pores are using monomers with greater compatibility with the polyolefin, and the larger - using monomers with less compatibility with the polyolefin. As used here, "compatible" means inter alia adhesion force at the interface between the two components after separation of the phases during cooling of the product.

When it is desirable to impart fire resistant properties to the product, it can also be easily implemented using a suitable monomer. More specifically, it may be used a monomer, substituted by bromine, such as dibromo or treprostinil or diacrylate of tetrabromobisphenol A.

It should be borne in mind that a given exhaust what can be the use of from 1 to 75 wt.%/wt. improving the fire resistance of the monomer in the monomer system, or from 0.2 to 60 wt.%/about. with respect to the polyolefin and the monomer.

The specialist in this area should be clear that the polyolefins are typically thermoplastic in nature. By use of suitable Monomeric systems in the methods of the present invention, for example Monomeric systems, which give a more or less significant amount of cross-linking, it is possible to essentially get the products based on the polyolefin, which are essentially thermoset.

Plasticizing monomers that may be used in accordance with this invention are primarily those which are solvents for the main polymer component (components) of the polyolefin product. It is not necessary that they were solvent and usually they are not solvents for either inorganic components or other components, which themselves may also be polymers, such as additives modifying impact resistance, texturemode additives, pigments and some additive that improves the compatibility of the components. The monomers should mainly be a long segment, which is "the Windows, in which the polymerized group is located at one end of the chain, since such monomers are generally much more reactive than those in which the group is inside the molecule. It is preferable to use monomers which have a molecular weight in the range from 200 to 5000, for example from 300 to 3000. Suitable "such polyolefin" structures are typically hydrocarbons with ten or more carbon atoms, and examples of such groups could be lauryl (C12H25and stearyl (C18H37). Such structures can be linear, branched or cyclic, partially depending on the structure of the polyolefin. Curable group may be simple unsubstituted double bond, such as 1-dodecene, or a more complex group such as methacrylate, as in sterilisability. Other curable groups that may be mentioned include esters of vinyl alcohols such as ministart and group substituted styrene such as p-isoborneol.

When the system include polyfunctional monomers, then from the monomer may be formed of a continuous cross-linked polymer system. Optionally may include additional generators RA is involved network) receive, when one of coppering systems (e.g., preexisting polyolefin and plasticizing the polymerized monomer) sew. When you sew the two systems, formed the UPU.

A particular advantage of the invention is that by use of suitable Monomeric systems in appropriate amounts in accordance with this invention the polyolefin can now be given a wide variety of physical properties, many of which were previously unattainable in polyolefin systems. Moreover, more flexibility is achieved through the use of mixtures of two or more different monomers.

Basically can be used as at least 20%, preferably from 30% to 70%, more preferably from 40% to 60 wt.%/wt. monomer in the mixture of polyolefin-monomer (excluding other additives, such as fillers and so on) depending on, among other things, from solubilizing properties of the Monomeric system. In this regard, it may also be noted that, when it is desirable to use a monomer to give specific properties such as fire resistance, but this monomer has a relatively weak solubilizing properties at the required temperature, then the necessary solubilizers characterwise properties, for example, the use of loyaltybrief for the introduction of treprostinil.

Basically it is also desirable to use monomers which for security reasons are acceptable high boiling point and acceptable high flash point preferably at least 125oC, most preferably at least 160oC.

Another factor influencing the choice of monomer, is the relative reactivity of the polymerized functional group in the monomer. Therefore, where desired relatively fast polymerization, and particularly suitable monomers include stearylamine, where a slower polymerization is appropriate or more appropriate, there may be used monomers such as 1-dodecen.

By an appropriate selection of the monomer system can be controlled morphology and, consequently, the material properties of the product in different ways. On the one hand, it is possible to vary the size and shape of the domains of polyolefin and polymerized monomer, and on the other hand, you can also adjust the nature of the domains polymerized monomer.

For example, when the polyolefin and the polymerized monomer have ausrechnen. However, when the sizes of the domains of the two components is less than about 200 nm, then get a relatively transparent material product, and if the domain size of about 100 nm or less, then the product material becomes essentially transparent. The dimensions of the domains can be achieved by using, for example, lauriemittiet in the polyolefin Exact 4038 from Exxon.

More importantly, the size of the domain of polyolefin and plasticizing the polymerized monomer may be subject to compatibility of the monomer to the polyolefin. This, in turn, depends on how close the different properties of plasticizing monomer, such as energy density cohesion, the ability to polarization and polarity, to the properties of the polyolefin. In addition, the amount of plasticizing monomer relative to the polyolefin and the amount of the copolymer obtained by the inclusion of the terminal double bond of metallocene polyolefin polymerized plasticizing monomer, can also affect the size of the domain. When materials are more or less strongly incompatible, then the domain may be determined largely by the size of the particles of the polyolefin in the mixture and may be several hundred microns. At high compatibility time can be adjusted, for example, to form essentially spherical domains in order to provide improved impact strength while maintaining thermoplastic nature of the product, where the polymerized monomer is essentially thermosetting in nature, but weakly or not at all then attached to the polyolefin, so that essentially saved thermoplastic character of the latter. This can be achieved through appropriate fit compatibility and adhesion at the interface of two phases with respect to each other. Further information about polymer compatibility is readily available from standard publications, such as the Chapter on "Control Phase Structure in Polymer Blends" by Dr. Don R. Paul in "Functional Polymers" by D. E. Berbgreister & C. R. Martin, published by Plenum Press ISBN 0-306-43203-x.

The material properties of the product can be significantly modified through the use of monomers which give polymers with the appropriate characteristics. For example, when it is desirable to increase the ultimate tensile strength and/or to modulate the hardness, then you need to enter such monomers as isobornylacrylat, which give polymers with high TD (glass transition temperature), for example, up to 160oWith mostly plumeri, giving polymers with low TCR, for example below -80oWith mostly below -70oWith such as laurelcrest. Of course, you should be aware that AP polymer of the specific monomer may also vary to some extent by adding co monomer. This way you can also favorable to substitute, to a greater or lesser degree, other components such as inorganic fillers that may be included in order to improve the hardness, but to the detriment of other physical properties such as transparency, or flame-retardant additives, which tend to make the material of the product is undesirable brittle.

It should also be understood that through the use of polyfunctional monomers, such as monomers with more than one curable group, can be achieved a significant degree of cross-linking which has a positive effect on the increase of the ultimate tensile strength and % elongation at fracture. Typically, the monomer system contains from 2 to 20 wt. %/wt. polyfunctional monomer, preferably from 5 to 15 wt.;/wt.

In order otvetit or polimerizuet plasticizing monomer or monomers, in pestiviruses Monomeric si and elevated temperatures, essentially, for example, at least on the 20oC, preferably by at least 40oC, most preferably at least 50oC, higher temperature conditions of formation of the product, or when exposed to suitable radiation. In the latter case, it should be considered that the polymerization of plasticizing monomer may not require any increase in temperature above that which meets the conditions of the molding product. Optional also cross-linking monomers can be included in the plasticizing monomer system in order to facilitate curing and to provide improved properties.

Many classes of generators of free radicals can be used, but particularly useful are materials from the collections peroxide, ketone peroxide, peroxycarbonates, complex PROXIFIER, cumene hydroperoxide, and peroxyketal. Among suitable are also different classes of azo compounds and a variety of photoinitiator. When the initiators are present during the phase of the molding product, this then implies that the necessary characteristics of these compounds are such that they remain essentially dormant during pervonachalnogo free radicals with speed, which will be initiated polymerization of the monomer, for example, when the overall temperature or when they are subjected to suitable radiation. For example, material such as tert-butyl-perbenzoate has half survivability over 1000 h at 100oC, while at 160oC his half survivability less than 2 minutes

In the system of the polymer/monomer containing such initiator, it would be possible to rework the system in the form of the finished product (i.e., having the form or configuration) at 100oAnd then otvetit system by short curing at 160oC.

You can also use more complicated initiating systems in order to control the polymerization process. So, for example, by grafting on the polymer chain of the polyolefin maleic anhydride or any other suitable part of the molecule, which in itself is capable of generating free radicals or which can be converted into a portion of the molecule, generating free radicals, we can ensure that polymerization will begin selectively grafted on this part on the polyolefin chain. As a result of this increased binding between the polyolefin and the polymerized monomer, christic. For example, when maleic anhydride grafted on the polyolefin chain, it can then be subjected to reaction with tert-butylhydroperoxide in the usual way via thermal reactions proceed at about 120oWith in order to obtain the corresponding complex perefer, which can generate free radicals at elevated temperatures.

In this case, an additional benefit is that, because of tert-butylperoxide, which itself is used as a generator of free radicals, has a one-hour half-period survivability at about 199oWith corresponding complex perefer has a substantially lower temperature one-hour half-period survivability 119oWith that allows the polymerization at a lower temperature.

Another advantage of the use of such two-stage triggering system is that half survivability is significantly longer than for one tert-butylhydroperoxide, so that the mixture of the polyolefin-monomer is more resistant to premature initiation and polymerization, and therefore has a longer persistence in the tank", which allows to extend the imerissia.

To prevent premature polymerization of plasticizing monomer may be useful to add to the system an additional inhibitors. Most commercial monomers provide inhibitors to prevent polymerization during transport and processing. The content of such inhibitors could be increased to compensate for the time in the mode of forming polyolefin polymer product, for example in the modes used for forming the primary polyolefin polymer in the form of a sheet or in any other shape or configuration. In this regard, the temperature is usually the most important factor, but other conditions may also have to do with it. For example, stearyl-methacrylate commercially comes with 275 hours per million (million hours) simple nanometrology ether of hydroquinone (MAGH). Depending on time and temperature may be necessary to introduce 1000 hours at million MAGH or more. For this purpose, can be used inhibitors of a wide range of chemical families.

If desired, the initiator can be introduced only in the mixture of polyolefin and a plasticizer monomer after phase molding product, although it is essentially mimes molding product.

Polymerization of plasticizing monomer can essentially hold in any conditions suitable for the used of the polymerized Monomeric system. In the case of thermally activated system, it will be high enough temperature to generate adequate revenues of free radicals: basically, when the initiator has a half-life vitality 15 min or less at the temperature of polymerization. For example, when using peroxide or azide initiator, a suitable polymerization temperature could be approximately 180oC, and the temperature of the molding product will be essentially limited to no more than 130-140oC. In the case of the initiator that is activated by radiation (for example, using UV, gamma radiation or electron beam), the temperature will be substantially less significant factor and elevated temperature molding product, which can then be used, subject to possible limitations due to the sensitivity of the polyolefin and plasticizing monomer themselves to such high temperatures and/or because of the risk of unwanted activation of residual activator after receiving the original polyolefin.

Polymerization is essentially proweb to prevent the evaporation of volatile components in the mixture system of the polyolefin-plasticizer monomer.

Polymer system and monomer system can be combined in various ways to receive plasticized material with low viscosity (at least at elevated temperatures), which can be used to produce many types of products using several different manufacturing techniques. Combining solid and liquid components may be made of any suitable way, for example using a mixer constant or intermittent, various types of mixing devices, constant or intermittent, and various types of extruders. In all of these types of equipment solid components are mixed together at a sufficient temperature and with sufficient shear to achieve both a distributive and dispersive mixing. Fluid is injected at the required temperature and stige to dissolve the major polymer components and to achieve a good distribution of mixing and dispersive mixing of insoluble components from the resulting liquid. The liquid system is then maintained at a temperature that maintains the necessary fluidity for the manufacture of the final product form. Basically, this is La production of the final form of the product, include coverage smearing, injection molding, casting without pressure (fill) coating the fibers, coating by spraying, porous layer and a porous casting. The types of products that can be obtained by coating the anointing include: upholstery, automotive, roofing material, fabric for clothing, coverings for walls, flooring, carpet backing, paper coating and the coating roller. Centrifugal molding can be used to produce items such as storage tanks, containers, Luggage, containers, syringes and inflatable toys. Coating by dipping may be used to manufacture gloves, mesh racks, handles of tools and components of electrical devices. The coated fibers can be used to cover grids for applications such as insect; coating spray can be used to produce protective coatings on the fixtures and furniture; porous coating can provide PROSYSTEM for fabrics, carpet canvas and upholstery; and forming foams can be used for the manufacture of bumpers, porous pads, floating devices and isolation. You may also use the invention in respect of the shrinking or solid mixture otherwise pulverized to powder form, which can then be applied to the product for its cover, mainly, in a known manner, for example, by spraying the powder on the hot product.

Moreover, these granules (or powder) of a mixture of polymer-monomer can be used in other manufacturing techniques such as injection molding to obtain high-tech plastics from polyolefins, which previously could not be satisfactorily molded by injection molding.

Further preferred features and advantages of the invention will become apparent from the following detailed example is given for illustration.
