Abstract Novel polycarbosilazanes possessing Si−CH2 Si N linkage in their backbone are described. Their preparation involves thermal cross-linking of poly[(dimethylsilylene)-co-(1,3-dimethyl-1,3-disilazane)]s at 300 350 C. Thus, under controlled conditions, soluble and fusible preceramic polymrs were obtained. Upon pyrolysis, these materials gave good yields of silicon carbonitride-based ceramics containing low free carbon percentages and controlled nitrogen proportions.
