FIELD: chemistry.
SUBSTANCE: invention relates to a rubber composition which is capable of curing. Composition contains a rubber component, a filler and a curing agent, the rubber component including a block copolymer of polybutadiene and polyisoprene, wherein the block copolymer has content of cis-1,4 bonds of at least 90 %. Also disclosed are a tire component, a method of producing block-copolymers of polybutadiene and polyisoprene (embodiments).
EFFECT: invention enables to obtain a composition with improved wear resistance and low loss of hysteresis in vulcanisation.
