MIXTURES OF AMINOSILYL-FUNCTIONALIZED STYRENE, THEIR PRODUCTION, AND THEIR USE IN PRODUCTION OF ELASTOMERIC COPOLYMERS Russian patent published in 2022 - IPC C07F7/10 C08F236/10 B60C1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to mixtures of specific styrene derivatives and their use in the production of elastomeric copolymer. A mixture of two or more styrene derivatives for the production of copolymer, described by the formula (I), is proposed, where n is 0 or 1; R¹ and R² can be the same or different and are an alkyl group containing from 1 to 10 carbon atoms; and R³ and R⁴ can be the same or different, and each of R³ and R⁴ is independently an alkyl group containing from 1 to 10 caron atoms. A method for the production of the specified mixture of styrene derivatives, the use of the specified mixture, methods for the production of a copolymer component and elastomeric copolymer, elastomeric copolymer, a method for the production of rubber from it and corresponding rubber, a rubber composition, and a tire component from it, as well as a tire itself are also proposed.

EFFECT: elastomeric copolymers obtained from the proposed mixture of styrene derivatives have good compatibility with such fillers as technical carbon and silicon dioxide, as well as increased hydrolytic stability, which allows for the production of rubber and products of it with improved physical and chemical and operational characteristics.
