CARBORANE-(SILANE OR SILOXANE)-UNSATURATED POLYMERS

摘要

This invention relates to a new class of novel inorganic-organic hybrid polymers that are formed from linear inorganic-organic hybrid polymers of varying molecular weight. These new high temperature oxidatively stable thermosetting polymers are formed from linear polymeric materials having repeat units that contain at least one alkynyl group for cross-linking purposes and at least one bis(silyl or siloxanyl)carboranyl group. These novel organoboron thermoset polymers contain an unsaturated cross-linked hydrocarbon moiety. These inorganic-organic hybrid polymers can be further converted into ceramics at elevated temperatures to prepare engine parts, turbine blades and matrices.
