HYDROSILYLATION PROCESS FOR PREPARATION OF NOVEL CHLORINE END-TERMINATED ORGANOSILOXANES

摘要

HYDROSILYLATION PROCESS FOR PREPARATION OF NOVEL CHLORINE END-TERMINATED ORGANOSILOKANES The present invention is for chlorine endterminated organosiloxanes and a hydrosilylation process for their preparation. The process comprises contacting a chlorine end-terminated (organohydrogen)siloxane and an a-olefin in the presence of a platinum catalyst, at a temperature of 50.degree.C. to 200.degree.C. The products of this process are unexpectedly chlorine end-terminated organosiloxanes.
