The conversion of polydimethylsilanes into the corresponding polycarbosilanes has been studied using liquid monomeric catalysts such as B(OR)3 (R = Me, Pr, SiMe3) or the B-N bonded compounds: Me2BN(SiMe3)2 and B(NEt2)3.Using this route it is possible to obtain polycarbosilanes which are more stable than the Mark III synthesized by the Yajima route and have a smaller polydispersity.These precursors obtained at 380-400 deg C do not require the use of an autoclave.
