PREPOLYMERS OF SILICON CARBIDE CERAMIC POLYMERS THE SILICON CARBIDE POLYMERS SILICON CARBIDE POLYMER-CONTAINING MATERIALS AND METHODS OF MAKING THE PREPOLYMERS POLYMERS AND POLYMER-CONTAINING MATERIALS

摘要

Pre-polymers which are alkoxylated or phenoxylated methylpolysilanes are useful for the preparation of fine grained silicon carbide ceramic materials and silicon carbide-containing ceramics. The pre-polymers exhibit ease of handling and their use to obtain silicon carbide ceramic materials results in high yields.
