Abstract:

Polycarbosilanes, in their broadest definition, are organosilicon polymers whose backbone is composed of silicon atoms, appropriately substituted, and difunctional organic groups which bridge the silicon atoms. The polycarbosilanes may be linear, or they can be cyclic or polycyclic. A review of polycarbosilanes with emphasis on polysilmethylenes is presented. Also covered are the Yajima and Bayer AG polycarbosilane precursors for Silicon Carbide.
