Title: Organosilicon compositions from cyclosiloxanes

Abstract: A method of preparing organosilicon compositions by heating various mixtures of (i) dimethylcyclosiloxanes or methylhydrogencyclosiloxanes, (ii) homopolymeric and copolymeric cyclosiloxanes containing a C5 or more carbon atom containing group, and (iii) homopolymeric and copolymeric cyclosiloxanes containing an oxyalkylene segment, in the presence of a catalyst, at a temperature and for a time sufficient to cause polymerization of cyclosiloxanes (i) to (iii) to the desired organosilicon composition.
