HIGH TEMPERATURE THERMOSETS AND CERAMICS DERIVED FROM LINEAR CARBORANE-(SILOXANE OR SILANE)-ACETYLENE COPOLYMERS

摘要

This invention relates to a new class of inorganic-organic hybrid thermosetting polymers and ceramics that are formed from new linear polymers of varying molecular weight and varying carborane content. These new organoboron thermoset polymers and ceramics contain an unsaturated cross-linking moiety and exhibit a differential scanning calorimetry plot of heat flow versus temperature in nitrogen obtained at a heating rate of 10 degrees celsius/minute, as shown in the Figure.
