Abstract
Preceramic polymers which have particular utility in providing protective ceramic coatings on carbon/carbon composites, graphite, carbon fibers, and other normally oxidizable materials are prepared by reacting about 0.25-20 parts by weight of a trialkyl- or trialkoxyboroxine in which the alkyl or alkoxy groups contain 1-6 carbons with one part by weight of a poly-silazane to form an organoborosilazane polymer.
