VINYLSILANES FOR USE IN FUNCTIONALISED ELASTOMERIC POLYMERS Russian patent published in 2018 - IPC C07F7/10 C08K5/5445 C08F236/06 C08L9/06 B60C1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to novel vinylsilane compounds that can be modifiers in the polymerisation of conjugated diene monomers to produce elastomeric polymers used in the manufacture of rubber products. Disclosed is a vinylsilane compound of formula (1), wherein R is independently selected from C₁-C₁₈ hydrocarbyl, R" is selected from C₁-C₆ hydrocarbyl; R_a, R_b and R_c each represents hydrogen; x and y are independently integers selected from 1 and 2; z is an integer selected from 0 and 1; and x + y + z = 3; R' is independently selected from C₁-C₁₂ alkyl, C₇-C₁₈ alkylaryl and tri(C₁-C₆ alkyl)silyl, where two R' groups can be combined to form a ring, and the ring may contain, in addition to the nitrogen atom bound to Si, oxygen or a group >N(C₁-C₆ alkyl). Versions of a method of producing said compound, an elastomeric polymer and a method for its production using the said compound, a cured composition of said polymer and a method for its production, as well as articles obtained therefrom are also provided.

(1)

EFFECT: technical result is the possibility of obtaining elastomeric polymers with reduced heat generation and improved elasticity, which enables to obtain rubber products with improved performance characteristics.
