      摘要:Dialkali metal organosilanolate and dialkali metal organosiloxanolate salts are manufactured from cyclic siloxanes or linear silicone polymers using a heterogeneous interfacial reaction process. A stoichiometric excess of an alkali metal hydroxide such as potassium hydroxide or an alkali metal oxide as a solid or dissolved or dispersed in a compatible solvent, is prepared and used as a first phase. The cyclic siloxane or linear silicone polymer is placed in a second phase either dissolved or dispersed in another solvent which is immiscible with the first phase. The resulting silanolate and siloxanolate salts can be used as monomers for solid-liquid phase and liquid-liquid phase interfacial polymerization or in a polycondensation process for the synthesis of alternating siloxane polymers. They can also be used as ring opening initiators for the base catalyzed polymerization of cyclic siloxanes.
