A method for preparing silazane polymers is disclosed which comprises reacting under transamination conditions: (A) one or more silicon amides represented by the general formula: ((R<1>)2N)a-Si(R)b wherein each R is independently hydrogen or a hydrocarbon group, a is an integer from two to four, b is an integer from zero to two and the sum of a and b equals four; with (B) one or more polymers. Also, disclosed are the silazane polymers produced by this method and silicon ceramics produced from these polysilazanes. |
