METHOD FOR PRODUCING MULTICOMPONENT COPOLYMER Russian patent published in 2018 - IPC C08F236/04 C08F236/10 C08F236/06 C08F210/02 C08F212/08 C08L9/06 C08F4/54 C08F4/6192 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for preparing a multicomponent copolymer. Method comprises copolymerising a conjugated diene compound, a non-conjugated olefin compound and an aromatic vinyl compound to form a multicomponent copolymer with a backbone with an acyclic structure. Polymerisation is carried out in the presence of a polymerisation catalyst composition comprising at least one metallocene complex.

EFFECT: technical result is a simplification of the technology of obtaining a multicomponent copolymer with a backbone with an acyclic structure to produce a polymer with high content of cis-1,4-bonds.
