ABSTRACT:
A process for manufacturing an organic silazane polymer which comprises reacting an organic silicon compound of the following formula (I): ##STR1## in which R represents hydrogen, chlorine, bromine, methyl radical, ethyl radical, phenyl radical or vinyl radical, R.sub.1 represents hydrogen or methyl radical and X represents chlorine or bromine, or a mixture of organic silicon compounds of the formula (I) above and an organic silicon compound of the following formula (II): ##STR2## in which R.sub.2 and R.sub.3 represent hydrogen, chlorine, bromine, methyl radical, ethyl radical, phenyl radical or vinyl radical and X represents chlorine or bromine with a disilazane of the following formula (III): ##STR3## in which R.sub.4, R.sub.5, R.sub.6 represents hydrogen, methyl radical, ethyl radical, phenyl radical or vinyl radical in an anhydrous state at a temperature of from 25.degree. to 350.degree. C. while distilling off by-produced organic ingredients out of the system to obtain an organic silazane polymer. The organic silazane polymer is useful for preceramic materials.
