Abstract
Star- and comb-type branched organosilicon compounds containing .omega.-terminated organopolysiloxane branches are readily synthesized by the catalyzed or uncatalyzed reaction of an at least tris(organyloxy)-functional organosilicon compound with a predetermined amount of substantially linear minimally disilanol-functional organopolysiloxane. Well defined, non-resinous, liquid products of low viscosity may be obtained.
