| 摘 要： | 采用MesiHCI2和Me（CH2=CH）SiCl2共氨解制备出流动性好的含Si-H和SiCH=CH2的低分子硅氮烷，结果表明H2PtCl6（脱水）和DCP是合适的硅氯化交联的催化剂和双键交联的引发剂。交联产物在程序控温的管式炉中裂解，得到高的陶瓷产率（＞74％wt）。

| Abstract: | A silazane oligomer with low viscousity and latent active groups(Si-H and Si (CH= CH2) ) was prepared by coammonolysis of MeSiHCl2 and Me (CH2 = CH) SiCl2.H2PtCl6(dehydrated ) and dicumyl peroxide (DCP) were found to be effective to catalyse or initialise crosslinking of the silazane oligomer respectively. The crosslinked polymer was pyrolysed in a tube furnace to obtain high yield(over 74 %wt)ceramic at 1273K. |

| Keywords: | silazane active group crosslinking pyrolysis |
