FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to copolymers of ethylene and butadiene. Invention describes a copolymer of ethylene and butadiene showing the mole content of butadiene derivative links as 8% or above wherein these links comprise bond as trans-1,2-cyclohexane and having the mean molecular mass Mn 40000 g/mole or above. Also, invention describes a catalytic system used for synthesis of copolymer of ethylene and butadiene that comprises the following components: (i) metalloorganic complex; (ii) co-catalyst belonging to group consisting of alkylmagnesium, alkyllithium, alkylaluminum, Grignard reagent, or consisting of a mixture of indicated components and wherein the mole ratio co-catalyst/metalloorganic complex is in the range from 1 to 8, and a method for synthesis of copolymer of ethylene and butadiene. Invention provides preparing copolymer of ethylene and butadiene showing the mole content of butadiene derivative links as 8% or above wherein indicated links comprise bonds as trans-1,2-cyclohexane and having high mean molecular mass.
EFFECT: improved method of synthesis.
