ABSTRACT:
The present invention relates to a method of producing silazane polymers with silicon functional groups attached to the nitrogen. The method comprises treating a silazane polymer containing an N-H bond with an alkyllithium and then reacting the resultant silazane polymer with a chlorosilane. The invention also relates to novel silazane polymers produced by the above process as well as the use of these polymers to form ceramic materials.
