Abstract : This invention relates to a new class of novel inorganic-organic hybrid thermoset 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 siloxanyl group. These novel thermosetting polymers can be further converted into ceramics at elevated temperatures.
