FIELD: chemistry.
SUBSTANCE: invention relates to an ethylene-butadiene copolymer containing statistically distributed ethylene units, butadiene units, trans-1,2-cyclohexane units. Molar ratio of ethylene links in copolymer is 50–99 mol % relative to total number of moles of links of ethylene, butadiene and trans-1,2-cyclohexane. Molar concentration of each of the links is constant throughout the copolymer chain. Also described is a method of producing a copolymer and use of a copolymer in rubber compositions for tires.
EFFECT: technical result is possibility of controlling degree of embedding of ethylene and butadiene and homogeneity of different links throughout chain, so as to obtain copolymers with low degree of crystallinity.
