FIELD: chemistry.
SUBSTANCE: invention relates to polymer compositions, in particular to polypropylene compositions. Composition contains isotactic polypropylene or its copoloymers with ethylene and polypropylene, modified with synthetic caoutchouc of Armlen brand, with their weight ratio equal 1-10:1. Products from claimed composition have higher physico-mechanical properties in wide range of temperature from (-)120°C to (+)170°C, which allows using them in conditions of Far North and permafrost.
EFFECT: increasing physico-mechanical properties of products obtained by casting under pressure.
