Abstract
Novel polycarbosilazanes possessing Si-CH2-Si-N linkage in their backb one are described. Their preparation involves thermal cross-linking of ethyl-silylene)-co-(1,3-dimethyl-1,3-disilazane)]s at 300-350 degrees C. Thus, under controlled conditions, soluble and fusible preceramic polymers were obtained. Upon pyrolysis, these materials gave good yiel ds of silicon carbonitride-based ceramics containing low free carbon p ercentages and controlled nitrogen proportions.
