Silane coupled polymers

摘要

A functionalized polymer includes a directly bonded moiety, which can be located at a terminus of the polymer, defined by the formula CR1R2NH—O—]—Si where each R1 and R2 independently is a substituted or unsubstituted hydrocarbyl group and where the Si atom can be bonded through similar moieties to up to three other polymers and/or to the appropriate number of non-interfering groups. The polymer can be provided by introducing a ketoximesilane compound into a system that includes carbanionic (living) polymer. Such polymers can be used in the production of compositions that include particulate fillers.
