Abstract
Polycarbosilanes in which some of the silicon atoms have been replaced by a hetero element selected from boron, titanium, zirconium, hafnium, etc. The hetero elements are incorporated into the polycarbosilane skeleton in such a way that, like the silicon atoms, they are bonded to the other parts of the polycarbosilanes via hydrocarbon bridges, and the polycarbosilanes are free of hetero element-oxygen-silicon bonds.
