| abstract |
Polymeric ethylene-bridged chlorosilazanes, process for their preparation, ceramic materials which can be prepared from them containing silicon nitride, and their preparation n The invention relates to novel polymeric ethylene-bridged chlorosilazanes, their preparation, their further processing to a ceramic material containing silicon nitride, and this material itself. In order to prepare the polymeric chlorosilazanes, oligosilazanes of the formula (I) ##STR1## are reacted with at least one of the chlorosilanes ##STR2## in which R 1 to R 5 are C 1 -C 6 -alkyl or C 2 -C 6 -alkenyl groups, which may be identical or different. n The polymeric chlorosilazanes according to the invention can be converted by reaction with ammonia into polysilazanes, which in their turn can be pyrolysed to ceramic materials containing silicon nitride. |
