FIELD: chemistry.
SUBSTANCE: invention describes compounded polymer comprising (a) polyamide and (b) polymer of an olefin-maleic anhydride obtained by copolymerising maleic anhydride and an olefin selected from group consisting of ethylene, propylene, isobutylene, butene-1, octene, butadiene, styrene, isoprene hexene, dodecene, dodecene-1 and tetradecene; wherein compounded polymer is prepared by compounding polyamide resin and olefin-maleic anhydride, where polymer is an olefin-maleic anhydride has a molar ratio of maleic anhydride to olefin of from 1:10 to 10:1 and wherein polymer is an olefin-maleic anhydride is present in a concentration of from 0.01 to 5.0 %. Also disclosed is a cross-linked polymer compounded, methods of producing a compounded polymer and compounded polyamide article comprising compounded polymer.
EFFECT: technical result consists in obtaining a compounded polymer with improved properties and performance characteristics, such as resistance to stretching, impact strength, creep resistance and resistance to degradation due to hydrolysis of antifreeze compound.
