Novel branched siloxanes, silicone release coating compositions containing the branched siloxanes, and silicone release modifier compositions containing the branched siloxanes comprise compositions having the formula: wherein R<SUP>a </SUP>is an alkyl group having 1-6 carbon atoms, an alkenyl group having 2-6 carbon atoms, or an alkynyl group having 2-6 carbon atoms; R<SUP>b </SUP>is an alkyl group having 1-6 carbon atoms, an alkenyl group having 2-6 carbon atoms, an aryl group, an alkoxy group, an acrylate group, or a methacrylate group; n is 1-200; and provided that at least 3.2-3.9 of the R<SUP>a </SUP>groups in the branched siloxane are alkenyl or alkynyl groups. |
