Abstract:

This invention relates to a new class of novel linear inorgantc-organic hybrid polymers of varying molecular weight that are useful for making high temperature oxida- tively stable thermosets, and these novel linear polymers arc in themselves oxidatively stable at high temperatures between 600 deg-1000 deg C. These new materials have repeat units that contain at least one alkynyl group and at least one siloxanyl group within the backbone of these novel linear polymers. These novel linear polymers can be further polymerized to form thermosets and ceramics.
