    The invention relates to a polythiol-finite composition m5, in particular, based on poly1 ethylene or polyprigene, propylene, modified by an interaction reaction with methylolphenol compounds. It is well known that olofinovge polymers can be modified, if the oxidized olefin polymer can interact with methylolane chemophenol compounds. It is important that the olefin monomer is oxidized to increase the content of carbonyl or cerexide in the olefinic polymer 5 before reacting with the ms solvent and the phenol compound 1j. Polymer COMPOSES-: CII based on the indicated modalized olefin polymer mode do not possess sufficiently high chizi: ko-moh1 Ts1 eskimi properties. The most b.pizko not; The technical essence of the invention is a polymeric composite 5 containing a polyolefin, for example polyethylene or polypropylene 5 and a polymer having an affinity for methylolphenol - gmi groups - synthetic rubber 2J. However, the well-known composition is lacking, but bw; socks the I and the bearing 1 (lp-5 lengthening, ,,,,. The purpose of the invention is to improve strength, strength, and relative elongation, position. The target is achieved by that. polymeric n, omisoyl; containing polyolefin li dolimer having affinity for methylolphenol groups, contains polyethylene or polypropylene as polyolefin with 1.96-3585 May.% grafted methylol phenol groups, and as a polymer having affinity for methylolphenol- w groups polymer selected from the group consisting of polymethyl terephthalate, copolymer of styrene with acrylocitrile, crystall poly hexamethylene adipate, polycapro, ethylene propylene rubber, and natural rubber in the following ratio of components, May,%: Polyolefin50 Polymer having affinity for methylpolyne resin; the methylolphenol groups can be grafted, they can b, 1 t, the interaction of the mono-olefin polymer with methylolpheno is irradiated by P1K11.

Particularly preferred: - tel. -nm methylolphenol compounds are derived from dimethylphenol mixed with Cj-Cd-Skyl groups, in particular, TH4F {fjiMH alkyl groups in the para position, Halogenated compounds can also be used, for example, broNo-tro 31
    Baths, methylolphenolic compounds. Halogenated compounds at elevated temperatures in the presence of a metal oxide, such as zinc oxide, form a Lewis acid as an activator in place. Suitable methylolphenol compounds are sold under the trade names SP-IOiS, SP-1055, SP-1056, CPJ 352 and Arofene resins et al.
    According to the invention, any activator can be used that promotes the grafting of the methylol} youth compound to the olefin polymer. Preferred activators are Lewis acids, including acid-active metal halides, for example boron trifluoride, tin chloride, zinc chloride, tri- or tetrachloride of titanium, chloride aluminum, ferric chloride, ferrous bromide, zinc bromide, aluminum bromide and complexes of it.
    The olefin polymer to which the methylolphenol groups are grafted is described. As the second component of the inventive composition, a polymer is used which has an affinity for mytilol phenol groups. In this case affinity means any attraction of the methylolphenol} b X groups, be it of a chemical or physical nature, which enhances compatibility between the two polymers. The second component of the polymer may have an affinity with methylol or hydroxyl groups, or with both groups. Due to the indicated affinity, a polymer mixture is obtained with improved properties, for example, with greater tensile strength, greater elongation at break, and better toughness.
    As ursaazingh polymers, the composition contains polytetramethylene terephthalate (RTMT), styrene-acrylonitrile copolymer (SA), polycaproamide (nylon 6), polyhexamethylene dyedtate (nylon 66), ethylene-propylene rubber (EPDM), and natural rubber (NP).
    From the proposed compositions can produce various molded, extruded or calendered products. They are particularly suitable for the production of products by extrusion, injection molding and various methods of injection molding. Properties of modified mixtures for 1214
    it depends on the number of components in the mixture, and it is possible to obtain a wide range of properties, changing only the amount of one or another component of the polymer.
    The properties of the composition under stress-strain are determined according to test methods of ASTM (ASTM).
    materials). Tensile tests are carried out with a sample in the form of a micro-dumbell (A5-TM 1708-66) 2.23 cm long. They work with an Instron-type tester, stretching samples
    during the tensile test and determine the final elongation. The test instrument is designed in such a way that it is possible to determine dimensional changes when tested on
    gap with clamping samples.
    The proposed composition is obtained by mixing the components in a Brabender type mixer at oil bath temperatures and at specified speeds.
    mix it up
    To obtain polypropylene with grafted methylolphenol groups of 100 may. polypropylene (Profas 67Z3) is fed to the mixer and transferred at 80 rpm to an oil bath of about 180 ° C. When the polypropylene is melted, add
    2mae. including dimethylol-p-octylphenol (SP - 1045) and continue mixing
    another 2 min. Then, as an actuator, 0.4 h of zinc chloride dihydrate is added and further stirred
    3 min. Next, 0.07 wt.h. magnesium oxides (to neutralize
    free acid), and the mixture is stirred by EE1, e for a minute. Then Maes is rolled into a shield. Material denote Graft RR-1.
    For the preparation of polyethylene with grafted methylolphenol groups of 100 wt.h. high density polyethylene (Marlex ENM 6006) is fed into the mixer and stirred at
    80 rpm at about 185-190 ° C. Added 4 May. including dimethylol-P-octylphenol and stirred for one more minute. 0.8 may be added as an activator. h with Ctj and stirred for another three minutes. 0.32 parts of magnesium oxide is added and mixed for another minute. The product is designated PE-1. Example 1. Mixtures are prepared by mixing the polymers in a Brabender type mixer at 80 rpm and at an oil bath temperature of about 225 ° C for polymer compositions 1-6 and 180 ° C for compositions 7 and 8. When the polymers are molten, the mixture is mixed for 5 minutes The mixture is removed from the mixer and cooled, then placed back into the mixer and the melt is stirred for another 2 minutes. Prototypes were prepared by pressing in mixtures at 250 ° C for compositions 1-6 and at 225 ° C for compositions 7 and 8. The control compositions are also prepared, using polypropylene or polyethylene. From the data in Table 1, it can be seen that mixtures containing polyolefin with grafted methylolphenol groups, possess improved properties, for example, increased tensile and tear strength. Improved properties indicate increased compatibility between both polymers. Example 2. A mixture of polymer and grafted polypropylene is obtained by mixing the polymers in an iHna Brabender mixer at 80 rpm and at 180 ° C for two minutes after the grafted polypropylene melts. The mixture is removed from the mixer and cooled, then placed back into the mixer, and the melt is stirred for another two minutes. Prototype samples were prepared; press the mixture in molds at about 220 ° C. Control rubber mixtures were also prepared using polypropylene. Ethylene-propylene mixtures are obtained from ethylene-polypropylene nororborene copolymer (Epsyn 70 A). Mixtures of natural rubbers are obtained using natural rubber smoked sheeps. Properties of the compositions are given in Table B. 2. From the data table. 2, it can be seen that mixtures containing polypropylene with grafted methylolphenol groups have improved properties, for example, increased tensile and tensile strength, as well as high relative elongation. Improved properties indicate increased compatibility between both polymers. Table 1
