FIELD: production of synthetic rubber. SUBSTANCE: invention relates to synthetic rubber used in car tire industry, rubber and asbestos technical articles. Composition consists of (A) high-molecular statistical 1,2-polybutadiene of molecular mass 100 000-500 000 Da and (B) syndiotactic 1,2-polybutadiene at content of 1,2-links from 75 to 92% and molecular mass 10 000-100 000 Da used as modifying agent and crystallinity 5-50%. Ratio of components in composition, mas. p. p.: A:B = 100:(1-50). EFFECT: vulcanizable composition improves technical properties of rubber articles. 1 tbl
