Polycarbosilanes containing heteroatoms

Some of the silicon atoms in the polycarbosilanes have been replaced by hetero atoms. The hetero atoms are, in particular, from the group comprising boron, titanium, zirconium, hafnium and others. The hetero atoms are incorporated into the polycarbosilane skeleton in such a manner that they, like th...

Beschreibung
Zusammenfassung:	Some of the silicon atoms in the polycarbosilanes have been replaced by hetero atoms. The hetero atoms are, in particular, from the group comprising boron, titanium, zirconium, hafnium and others. The hetero atoms are incorporated into the polycarbosilane skeleton in such a manner that they, like the silicon atoms, are bonded to the remainder of the polycarbosilane via hydrocarbon bridges, and the polycarbosilanes contain no hetero element-oxygen-silicon bonds.
