FIELD: chemistry.
SUBSTANCE: claimed invention suggests method of regulating structure of copolymer chain. Method of regulating structure of chain of copolymer of conjugated diene compound and non-conjugated olefin is realised in the following way. Introduction of conjugated diene compound in presence of non-conjugated olefin and polymerisation catalyst is regulated to regulate copolymer chain structure, and where polymerisation catalyst includes composite metallocene-based catalyst, represented by the following formula (A): RaMXbQYb … (A), where each of R independently represents non-substituted or substituted indenyl group, with R being coordinated with M, M represents lanthanide element, scandium or yttrium; each of X independently represents hydrocarbon group, containing from 1 to 20 carbon atoms, with X µ- being coordinated with M and Q; Q represents elements from group 13 in periodic table; each of Y independently represents hydrocarbon group, containing from 1 to 20 carbon atoms, or hydrogen atom, with Y being coordinated with Q; and each of a and b constitutes 2. Method of regulation of copolymer chain structure, where copolymer of conjugated diene compound and non-conjugated olefin is represented by copolymer of butadiene and ethylene, is realised, and butadiene or butadiene and ethylene in said method are introduced into polymerisation reaction, in which ethylene polymerisation was initiated, or into system of polymerization reaction, in which polymerisation of butadiene and ethylene was initiated, or into system of polymerisation reaction, containing ethylene-butadiene copolymer, in presence of ethylene and polymerisation catalyst in such a way as to obtain block-copolymer, statistic copolymer or gradient copolymer.
EFFECT: provision of regulation of monomer unit location in copolymer with application of particular metallocene catalysts.
