polymethyl

Polyborazine-polymethylsilane(PBN-PMS) was obtained by reaction of PMS with 1%(mass fraction) PBN; and then soluble polymeric precursor PBN-PCS-PMS was prepared by hybridization of the PBN-PMS with a suitable amount of PCS(polycarbosilane).

聚碳硅烷 (PCS ,—CH2 —SiH(CH3)— )与聚甲基硅烷 (PMS ,—SiH(CH3)— )是目前主要的 2种碳化硅前驱体聚合物[3] 。

Polymethylsilane (PMS) is the simplest polysilane; it can be synthesized by Wurtz reductive coupling reaction of methyldichlorosilane in different solvent systems.
