Title:
ORGANIC SILAZANE POLYMER AND PRODUCTION OF CERAMICS USING SAID POLYMER
Document Type and Number:
Japanese Patent JPS63193930
Kind Code:
A
Abstract:

PURPOSE: To obtain an organic silazane polymer suitable as a precursor for ceramics, by ammonolyzing a specific mixture of organic silicon compounds and polymerizing the reaction product in the presence of a basic catalyst.

CONSTITUTION: The objective organic silazane polymer can be produced by reacting (A) a mixture of (i) an organic silicon compound of formula I and/or formula II (R is H, Cl, Br, CH3, C2H5, phenyl or vinyl; R1 is H or CH3; R2 is H, CH3, C2H5, phenyl or vinyl; X is Cl or Br) and (ii) an organic silicon compound of formula III with (B) ammonia and polymerizing the resultant ammonolysis product in the presence of (C) a deprotonizable basic catalyst.
