Ceramics formed by pyrolysis of either linear or thermosetting carborane (siloxane or silane) acetylene based precursor polymers

摘要

Ceramics that are formed from high temperature oxidatively stable thermosetting polymers which, in turn, 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.
