FIELD: chemistry.
SUBSTANCE: invention relates to an ethylene and butadiene copolymer containing statistically distributed ethylene links and butadiene units, wherein molar ratio of ethylene links in said copolymer is 50–99 mol % relative to total mol number of ethylene links and butadiene units. Molar concentration of each of the links is constant throughout the length of the copolymer chain. Also described is a semicontinuous method of producing an ethylene and butadiene copolymer and a tire production composition.
EFFECT: technical result is possibility of controlling degree of inclusion of ethylene and butadiene and homogeneity of different links along entire length of chain.
