ORGANIC-INORGANIC HYBRID PREPOLYMER AND PROCESS FOR PRODUCTION THEREOF

摘要

With the aim of obtaining an organic-inorganic hybrid prepolymer and an organic-inorganic polymer (a product of gelling of the prepolymer) which are free from clusters of an inorganic component, provided is an organic-inorganic hydrid prepolymer which is produced by reacting a polydimethylsiloxane that has one or two terminal silanol groups with a metal and/or semimetal alkoxide oligomer through polycondensation accompanied with hydrolysis to introduce the metal and/or semimetal alkoxide to one or both terminals of the polydimethylsiloxane.
