ABSTRACT:
This invention relates to a new class of novel linear inorganicorganic hybrid polymers of varying molecular weight that are useful for making high temperature, oxidatively stable thermosets, and these novel linear polymers are in themselves oxidatively stable at high temperatures between 600.degree.-1000.degree. C. These new materials have repeat units that contain at least one alkynyl group and at least one bis(silyl or siloxanyl)carboranyl group within the backbone of these novel linear polymers. These novel linear polymers can be further polymerized to form thermosets and ceramics.
