    • The present invention is novel organofunctional polysiloxane and organofunctional cyclosiloxane compositions and a process for their preparation. The process for preparation of these siloxane compositions comprises contacting a mixture containing a cyclo(organohydrogen)-siloxane or a poly(organohydrogen)siloxane, a mono-.alpha.-olefin, a .alpha.,.OMEGA.-triene, and a triorganosilyl source, with a platinum catalyst, at a temperature within a range of 50.degree. C. to 200.degree. C. The products of this process are organofunctional polysiloxanes and organofunctional cyclosiloxanes.
