Abstract
The invention provides terminally reactive polysilanes of the formula: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are independently alkyl groups or aryl groups, X is a hydrogen or alkenyl group, n, m and k are 0.ltoreq.n.ltoreq.10, 0.ltoreq.m.ltoreq.10, n+m.gtoreq.10, and k.gtoreq.1, especially hydrosiloxy or alkenylsiloxy-terminated polysilanes. They are prepared by reacting hydroxy-terminated polysilanes with dialkylhydrochlorosilanes, alkylarylhydrochlorosilanes, dialkylalkenylchlorosilanes or alkylarylalkenylchlorosilanes in the presence of amine.
