ABSTRACT:
Preceramic polymers are prepared by mixing an organosilicon oligomer or polymer containing a multiplicity of Si--H and/or Si--N functional groups with a borane in an organic solvent for a sufficient time for the reactants to react, wherein the molar ratio of the organosilicon polymer repeat unit to borane is 15 or less.
