FUNCTIONAL POLYDIENE, METHOD FOR PRODUCTION THEREOF AND RUBBER COMPOSITION CONTAINING SAME Russian patent published in 2016 - IPC C08F8/42 C08C19/20 C08C19/25

Abstract RU 2599641 C2

FIELD: chemistry.

SUBSTANCE: invention relates to functional polydienes, methods for production thereof and compositions based thereon. Disclosed is a functional polydiene, which contains at least one type of conjugated diene structural units and silane binding functional units in their molecular chain, of formula (I), average molecular weight of functional polydiene ranges from 50,000 to 1,000,000; R₁-R₃ is a C₁-C₅ linear or branched alkyl or a linear or branched alkoxyl, and R₄ is a C₁-C₅ linear or branched alkylene. Invention also discloses a method of producing a functional polydiene and a rubber composition, containing a functional polydiene.

EFFECT: technical result is improved ratio between resistance to wet sliding and rolling resistance functional polydiene; reduced unpleasant odour, formed when mixing rubber by adding a silane binding agent.
