rubber industry. SUBSTANCE: filled polymer composition contains 100 wt parts of linear butadiene/styrene copolymer with bound styrene content 29 +/- 2 wt %, wherein butadiene and styrene units are distributed in macromolecule in blocks or statistically, 2,0-60.0 wt parts of filler: carbon black with specific geometric surface 15-100 sq.m/g, and 0.2-3.0 wt parts of modifier: hexahydrophthalic acid. In case of statistic distribution composition also contains vulcanizing group. EFFECT: increased strength and hardness and lowered hysteresis. 2 cl, 4 tbl, 28 ex
