- 1 - Abstract of the disclosure: HOE 87/F 302 Polymeric hydridochlorosilazanes and processes for their preparation The invention relates to novel polymeric hydridochloro- silLazanes and a process for their preparation. The com- pounds according to the invention can be converted into polyhydridosilazanes by reaction with ammonia, and these can in turn be pyrolyzed to ceramic material containing silicon nitride. To prepare the polymeric hydridochloro- silazanes, oligohydridoalkylsilazanes (R1SiHNH)n are reacted with a dichlorohydridoalkylsilane R2SiHCl2.
