FIELD: chemistry.
SUBSTANCE: rubber composition comprises a copolymer, a rubber component, at least, one component selected from the group consisting of technical carbon having an average particle size of 5 to 100 nm and silica having an average particle size of 0.5 to 200 nm. The copolymer comprises a monomer unit (a) formed from butadiene, and a monomer unit (b) formed βfrom farnesen. A tire is also described, in which a rubber composition is used.
EFFECT: providing a copolymer capable of improving the dispersibility of carbon black and silicon dioxide in the rubber composition with the use of the copolymer as part of the rubber composition, improving the technological properties of the rubber composition during mixing, moulding or vulcanizing, providing excellent rolling resistance and wear resistance with little mechanical strength and hardness deterioration in rubbers on its base.
