Title:
PRODUCTION OF NOVEL SILICON-CONTAINING PRECERAMIC POLYMER
Document Type and Number:
Japanese Patent JPS62201933
Kind Code:
A
Abstract:
A method of forming preceramic polymers by mixing (A) a methylpolysilane of the formula [(RSiH)x(RSi)y]n, (where R is a lower alkyl group having from 1 to about 6 carbon atoms, a cycloalkyl group having from 3 about to 6 carbon atoms, a substituted or unsubstituted lower aryl group having from 6 to about 10 carbon atoms, a tri(lower)alkyl- or di(lower)alkylsilyl group x+y=1, (x and y are each >0 and also x=l, y=o), and n is an integer greater than 1 with (B) an organic or organisilicon compound having at least two alkenyl groups and allowing the mixture to react is disclosed. Preferably, the alkenyl group is a vinyl group. The reaction is preferably initiated by the generation of reactive free radicals. Novel preceramic polymers formed by this method are also disclosed.
