摘要：

A series of alkyl- and arylsilsesquiazanes left bracket RSi(NH)//3/////2 right bracket was prepared by the ammonolysis of the corresponding RSiCl//3. Each polymer was pyrolysed to 1200 degree C in an inert atmosphere to give amorphous Si-C-N ceramic chars. Mechanistic aspects correlating the alkyl/aryl group on the polymer structure, decomposition and ceramic char composition were studied. Oxidative stability of the ceramic chars fits percolation theory.
