Abstract
Terminally reactive polysilanes of formula (1) are novel. ##STR1## R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are independently C.sub.1-12 alkyl or aryl groups, R.sup.5 is an organic group containing an alkoxysilyl, epoxy, glycidyloxy, acryl, methacryl, acetoxysilyl or amino group, A is a C.sub.2-6 alkylene group, n, m and k are numbers in the range: 0.ltoreq.n.ltoreq.10, 0.ltoreq.m.ltoreq.10, n+m.gtoreq.10, and k.gtoreq.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.
