FIELD: chemistry.
SUBSTANCE: invention relates to obtaining heterophasic copolymer. Active polymer from first polymerisation reactor is introduced into second polymerisation reactor. Contact of active polymer with at least one olefin is performed in polymerisation conditions in second polymerisation reactor with obtaining heterophasic copolymer, which has value of copolymer fraction (Fc) from 10 wt % to 50 wt %. Multicomponent antifoulant is introduced into second polymerisation reactor at such a rate that multicomponent antofoulant is present in heterophasic copolymer in concentration from 1 ppm to 100 ppm. Antifoulant represents multicomponent antifoulant and/or coating preparation.
EFFECT: obtaining impact copolymer with high content of caoutchouc with small adhesion and agglomeration of particles.
