Terminally reactive polysilane and process for making

摘要

Terminally reactive polysilanes of formula (1) are novel. (1) R1, R2, R3, and R4 are independently C1-12 alkyl or aryl groups, R5 is an organic group containing an alkoxysilyl, epoxy, glycidyloxy, acryl, methacryl, acetoxysilyl or amino group, A is a C2-6 alkylene group, n, m and k are numbers in the range: 0/=10, and k>/=1. The polysilanes are prepared by effecting addition reaction between a hydro-terminated polysilane and an unsaturated group-containing reactive compound in the presence of a hydrosilylation catalyst.
