FIELD: chemistry.
SUBSTANCE: invention relates to an oil-extended functionalised styrene-butadiene copolymer in which the functionalised styrene-butadiene copolymer contains 15-50% by weight, based on 100% by weight of the copolymer, repeating structural units based on styrene, 42-80% by weight, based on 100% by weight of the copolymer, repeating structural links based on butadiene and 5-43% by weight, based on 100% by weight of the copolymer, structural units based on at least one functional monomer, and wherein at least one oil filler is an oil based on vegetable oils, wherein the functional monomer is selected from a group consisting of acrylate-based monomers, as well as to a method for its preparation. Invention also relates to a rubber composition comprising said copolymer and its use for the manufacture of technical products.
EFFECT: technical result is the improvement of chemical processing in conditions of enterprises specialising in rubber compounding.
