Hydrolysable Silanes

摘要

This invention relates to hydrolysable silanes useful in the modification of elastomers, and as coupling agents for diene elastomer compositions containing a filler. In particular the invention relates to novel hydrolysable silanes containing a tertiary amine group and an ether or thioether linkage.

1. A hydrolysable silane of the formula wherein each R represents a hydrolysable group; each R″ represents a hydrocarbyl group having 1 to 8 carbon atoms; n=1 to 3; Y represents a divalent organic spacer linkage having 1 to 20 carbon atoms; X represents —O— or NH—; m=0 or 1; R1 represents a hydrocarbyl or substituted hydrocarbyl group having 1 to 20 carbon atoms; R2 represents hydrogen or a hydrocarbyl or substituted hydrocarbyl group having 1 to 8 carbon atoms; Z represents an oxygen or sulphur atom; and R3 represents a hydrocarbyl or substituted hydrocarbyl group having 1 to 20 carbon atoms, provided that when R3 is CH3, Y contains at least 2 carbon atoms.
