The invention relates to compositions containing an organic material subject to erosion due to oxidative, thermal processes or under the influence of light or sunlight, in particular polyolefins, such as, for example, polyolefin fibers, and as a stabilizer at least one compound of the type benzofuran-2-ones and less of the content of inorganic fillers materials resistance to decay, caused by oxidative, thermal processes or exposure to light or sunlight.

The use of compounds of the type benzofuran-2-ones as stabilizers for organic polymers is known, for example, from U.S. patent 4325863, 4388244, 5175312, 5252643, 5216052, 5369159, 5488117, 5356966, 5367008, 5428162, 5428177 or 5516920.

Spatial amines employed, and among them, in particular, compounds containing the group 2,2,6,6-tetramethylpiperidine, known as antioxidants, protecting from the action of light or sunlight ("Hindered Amine Light Stabilizers"; HALS).

Known stabilizers are not responsible in each case the high requirements that must be met stabilizer, in particular in relation to stability during storage, water absorption, susceptibility to hydrolysis stabilization during processing, behavior staining, volatility, migration characteristics, compatibility and improved protection from the action of light or sunlight. Therefore there is a need for effective stabilizers for organic materials, in particular polyolefins, such as, for example, polyolefin fibers, susceptible to destruction in the oxidative, thermal processes and/or vozdeystviyna difficult phenols in combination with compounds from the group of organic phosphites or phosphonites and if necessary, optionally with the use of antioxidants, protecting from the action of light or sunlight. The use of such stabilizing mixtures leads in many cases to yellowing of the obtained polyolefin fibers, particularly when exposed to a gaseous mixture of nitric oxide formula NOxin practice this is called "gas fading". Often the color change is also at the stage of processing, particularly during extrusion of the softened material. In addition, it is known that compounds from the group of spatial difficult amines which are optionally added as antioxidants, protecting from the action of light or sunlight, have an antagonistic effect with spatial dull phenols, which affects long-term heat resistance.

So, it was found that the stabilizing mixture containing at least one connection type benzofuran-2-ones and at least one connection type spatial difficult amines, particularly suitable as stabilizers for organic materials susceptible to destruction in the oxidative, thermal processresult excellent stabilization of polyolefins during processing, for example, to obtain polypropylene fibers. These stated stabilizing system inhibit the color change of the organic materials in the process, have excellent activity against the resistance OFx(no "gas fading") and demonstrate, in addition, improved long-term heat resistance is relatively stabilizing systems containing phenolic antioxidants. Spatial employed amines, replacement phenolic long-term thermal stabilizers, provide additional good protection from destruction of organic material in the oxidative process.

The proposed invention relates, therefore, to compositions containing

a) a polyolefin, subject to destruction in the oxidative, thermal or light, or sunlight,

b) at least one connection type benzofuran-2-ones

c) at least one compound from the group of spatial difficult amines, in a weight ratio of (b) to (C) is from 100:1 to 0.01:100.

The proposed invention also relates to compositions comprising in addition to components (a), (b) and (C) optional (d), menshy, containing as component (b) compound of formula 1

The mixture of components (b) and (C) or (b), (C) and (d) suitable to stabilize organic materials, in particular polyolefins, to splitting as a result of oxidation, heating or exposure to light or sunlight.

Examples of such materials are:

1. Polymers of mono - and diolefins, for example polypropylene, polyisobutylene, polybutene-1, poly-4-methylpentene-1, polyisoprene or polybutadiene, as well as polymerizate of cycloolefins, as, for example, cyclopentene or norbornene; furthermore polyethylene, which may optionally be cross-linked, for example high density polyethylene (HDPE), high density polyethylene and high molecular weight (HDPE-HMW), high density polyethylene and ultra high molecular weight (HDPE-UHMW), medium density polyethylene (MDPE), low density polyethylene (LDPE), low density polyethylene with a normal chain (LLDPE), (VLDPE) and (ULDPE).

Polyolefins, i.e. the polymers of monoolefins, as they mentioned, for example, in the previous paragraph, in particular polyethylene and polypropylene, can be obtained in various ways, in particular as follows:

a) radical method (usually at high pressure and high temperature IYb, Yb, YIb or YIII. These metals usually contain one or more related groups, such as oxides, halides, alcoholate, esters, ethers, amines, alkali, alkenyl and/or arily, which can be either-or-coordinated. These metal complexes can be free or bound to a carrier, for example with activated magnesium chloride, titanium chloride(III), aluminium oxide or silicon oxide. These catalysts can be soluble or insoluble in the medium, where the polymerization. Such catalysts can be active in the polymerization process, or may apply other activators, such as, for example, alkali, hydrides, alkylhalogenide, alkyloxy or alkyloxy metals, the metals being elements of groups Ia, IIA and/or IIIA. The activators can be modified, for example, simple groups, esters, amines or cyrilovich esters. Such catalyst systems are, as a rule, the following notation: Phillips, standard Oil Indiana, Ziegler (-Natta), TNZ (DuPont), Metallocen or Single Site Katalysatoren (SSC).

2.

4. Hydrocarbon resins (for example, C5-C9), including their hydrogenated mod is e preferred polyolefin fiber, in particular, polyolefin fiber, mostly free from phenols.

So, basically, free from phenols polyolefin fiber indicates that the number of phenolic antioxidants is less than 0.02 wt.%, in terms of the weight of the stabilized polyolefin fibers. These small amounts of phenolic antioxidants manufacturers of polyolefin added during manufacture to pre-stabilization of polyolefins.

It should be emphasized the activities of the stated components (b) and (C) or (b), (C) and (d) directed against thermal and oxidative destruction, primarily by thermal stress, which occurs during the processing of thermoplastics. Therefore, the claimed components (b) and (C) or (b), (C) and (d) serve as excellent stabilizers in the process.

The mixture of components (b) and (C) or (b), (C) and (d) is also suitable for imparting stability to polyolefins, which is in continuous contact with fluid extraction.

Component (b) best way is added to the stabilized organic material in an amount of from 0.0005 to 5%, in particular from 0.001 to 2%, for example from 0.01 to 2%, calculated on the weight of the stabilized organic material.
