HIGH TEMPERATURE CARBORANE-SILOXANE ELASTOMERS INTERMEDIATE POLYMERIC PRODUCTS AND PROCESS FOR PREPARATION

摘要

Abstract of the DisclosureCarborane-siloxane polymers are convenientlyprepared by the polymerization of a carborane disilanoland either a silyl diamine, a ureido-silane, or a silyldicarbamate. The resulting linear polymers are character-ized by relatively high molecular weights and are elasto-meric in nature. These gumstocks are compounded withsuitable fillers and additives and fabricated into curedelastomeric articles. The carborane-siloxane elastomersexhibit excellent high temperature properties which renderthem especially useful for a wide variety of applications,such as gaskets, seals, wire and cable insulation and thelike.- 1 -
