The scope of the invention

The present invention relates to the use of butyl yesterady polymers or partially halogenated butyl yesterady polymers, demonstrating effectiveness in reducing populations and/or prevent the accumulation of organisms. These organisms can be bacteria, algae, fungi, molluscs or arthropods. The present invention also relates to coatings for molded products containing the butyl insideradio polymers.

The level of technology

Poly(isobutylene-co-isoprene), or IIR, is a synthetic elastomer, commonly known as butyl rubber, which is from the 1940's get statistical cationic copolymerization of isobutylene with small amounts of isoprene (1-2 mol.%). Due to its molecular structure, isobutylene-isoprene rubber has a high impermeability to air, high ductility, oxidation resistance and high resistance to fatigue.

Butyl rubber is understood as a copolymer of isoolefine and one or more, preferably conjugated, multilatinas as co-monomers. Commercially available butyl rubber contains mostly souletin and a small amount, not more than 2.5 mol.%, conjugated multilatina. Butyl rubber or butyl polymer usually is about get the suspension technology using methyl chloride as a diluent and catalyst for Friedel-as part of the polymerization initiator. This method is further described in U.S. patent No. 2,356,128 and Ullmann''s Encyclopedia of Industrial Chemistry, volume A 23, 1993, pp. 288-295.

Halogenoalkane butyl rubber leads to the formation of reactive allylic halide functional groups of the elastomer. Conventional methods of halogenation of butyl rubber is described, for example, in Ullmann''s Encyclopedia of Industrial Chemistry (Fifth, Completely Revised Edition, Volume A231 Editors Elvers, et al.) and/or "Rubber Technology" (Third Edition) by Maurice Morton, Chapter 10 (Van Nostrand Reinhold Company © 1987), in particular on pages 297-300.

The presence of allyl halide functional groups allows the reaction of nucleophilic alkylation. Recently, it was shown that the treatment of the brominated butyl rubber (BIIR) nitrogen and/or phosphorus-containing nucleophiles, in the solid state, leads to the formation of yesterady polymers based on IIR, with interesting physical and chemical properties (see: Parent, J. S.; Liskova, A.; Whitney, R. A; Resendes, R. Joumal of Polymer Science, Part A: Polymer Chemistry 43, 5671 - 5679, 2005; Parent, J. S.; Liskova, A.; Resendes, R. Polymer 45, 8091-8096, 2004; Parent, J. S.; Penciu, A.; Guillen-Castellanos, S. A.; Liskova, A.; Whitney, R. A. Macromolecules 37, 7477-7483, 2004). Functional group insideradio polymer is formed by the reaction of nitrogen - or phosphorus-containing nucleophile and allyl halide fragments in the composition of BIIR, resulting in the formation of a charged ammonium or postnasal groups, respectively. Physical features the Ki obtained yesterady polymers on the basis of BIIR (strength of green material, elasticity, interaction with fillers and so on) are superior to the characteristics of their nonsteriodal polymer equivalents.

It was previously shown that the addition of para-methyl styrene to the mixture of raw materials for butilkoi polymerization (mixture of MeCI, isobutylene and isoprene, ll3/N2O as an initiator) yields a polymer with high molecular weight, containing up to 10 mol.% styrene groups, randomly included in the polymer chain (Kaszas, US 6,960,632; Kaszas et al. Rubber Chemistry and Technology, 2001, 75, 155). It was found that the introduction of para-methylstyrene occurs uniformly across the spectrum distribution of molecular masses, thanks to its close reactivity with isobutylene. Fragments of isoprene comprising butyl-terpolymers you can halogenate conventional methods, resulting in an allyl halide structures similar to the current halogenosilanes brands Type II and Type III Lanxess.

In SA 2,418,884 and 2,458,741 describes the obtaining of peroxide-cured compounds based on butyl rubber having a high content of multilatina. In particular, in SA 2,418,884 described continuous receipt of IIR containing isoprene from 3 to 8 mol.%. Halogenoalkane this butyl rubber with a high content of multilatina leads to the production of reactive allylic halide functional g of the SCP in the composition of the elastomer. Because currently you can reach such a high content of isoprene, in principle it is possible to generate BIIR analogues content of allyl bromidic functional groups of from 3 to 8 mol.%. Conventional methods of halogenation of butyl rubber is described, for example, in Ullmann''s Encyclopedia of Industrial Chemistry (Fifth, Completely Revised Edition, Volume A231 Editors Elvers, et al.) and/or "Rubber Technology" (Third Edition) by Maurice Morton, Chapter 10 (Van Nostrand Reinhold Company © 1987), in particular on pages 297-300.

Alternatively, butyl copolymer may contain From4-C7somnolin, such as isobutylene, and comonomer, such as parallel styrene, preferably para-methylsterol. After halogenation some of the alkyl groups present in the styrene monomer fragments contain benzyl halogen. Additional functional groups can be introduced by nucleophilic substitution of benzyl halogen various nucleophiles, as described in U.S. patent 5,162,445. The use of tertiary amines and phosphines leads to the formation of butyl yesterady polymers based on copolymers having improved physical properties.

Over the last few decades, continuous attempts have been made to develop polymers which inherently possess antibacterial, antifungal properties and/or can prepits is to facilitate reproduction of the algae, by impregnating antibacterial, antifungal and/or protivoopujolevami means. Such funds are usually low molecular weight compounds such as antibiotics, phenols, iodine, Quaternary ammonium compounds or heavy metals, such as silver, tin and mercury. These funds can be attractive, but provide limited protection because of the difficulty to control the rate of diffusion of the additive from the polymer matrix. This washout, ultimately, makes the material ineffective, represents a potential threat to the environment and potentially makes possible reactions washed material with other organic substances. In addition, the leaching of these tools in the environment increases the resistance of microorganisms to these tools.

Organic antibacterial, antifungal or protivovetrovye means limited to the introduction of the polymer compositions, as being organic, they usually have a boiling point lower than the temperature at which the formation of the polymer compositions. In previous studies it has been shown that polymeric compounds containing tightly bound antibacterial, antifungal or protivovetrovye funds oblad what are the advantages compared to polymeric compounds, which contain unbound conventional low-molecular equivalents. Connection with the well-known means have greater durability with low emission of toxic products in the environment, thereby reducing losses associated with evaporation, photolytic decomposition and transportation. In addition, the potential additional advantages are high efficiency, selectivity and safety when handling.

For other polymer systems, in which the antibacterial, antifungal or protivovetrovye means associated with the polymer, the introduction of the active substance in the polymer is often part of the process of polymerization, which can lead to problems in the production process and/or loss of properties of the polymer. In addition, modification of the polymer to introduce antibacterial, antifungal or protivosudorozhnogo funds may have a negative effect on the physical properties of the polymer, making the polymer less suitable for the intended use.

Although polymeric compounds containing antibacterial, were obtained and tested, it was found very few examples with the necessary anti-bacterial properties. In particular, the number of compounds active against gram is acteri, such as Escherichia coli and Salmonella, but very few compounds also exhibit activity against gram-positive bacteria such as Staphylococcus, Bacillus, Listeria and Streptococcus.

According to one object of the present invention monstergame polymer has antibacterial, antifungal and/or protivoopujolevami properties. Consider that this property insideradio polymer is a result of the ionic nature formed insideradio polymer. Although the authors of the present invention do not offer theoretical justification, they believe that the ionic properties insideradio polymer gives it antibacterial, antifungal and/or protivovetrovye properties that are not observed in typical halogenated butyl rubber.

As discussed above, antibacterial, antifungal and/or protivovetrovye supplements can be attractive, but have limitations related to the fact that their protective effect is often short on time, due to the complexity of controlling the rate of diffusion of antibacterial, antifungal and/or protivoopujolevoe additives from the polymer matrix. Leaching of additives from the matrix polimerov ultimately makes the material ineffective. In addition, leaching poses a potential threat to the environment and the risk of reaction is washed out of the material with other organic substances. The presence of ionic groups, covalently linked with the main chain of the polymer, as in yesterady the polymers of the present invention, eliminates the risks associated with leaching of additives and also potentially enhances the antimicrobial efficacy, selectivity and safety of working with polymer.

Described in this text monstergame polymer has advantages because it has the ability to post-modify a previously existing polymer, allowing you to control the polydispersity, molecular weight and topology of the polymer, which can sometimes change when during the polymerization are added antibacterial, antifungal or protivovetrovye funds.
