摘要

What is disclosed is a process for preparing R'3SiNH- containing silazane polymers by contacting and reacting organochlorosilanes with {R'3Si}2NH where R' is vinyl, hydrogen, an alkyl radical of 1-3 carbon atoms or the phenyl group. The silazane polymers are useful as chemical intermediates to produce silicon-containing chemical compounds. They are also useful in the formation of silicon carbide-containing ceramic materials.
