摘要：

Polycarbosilane was synthesized from polydimethylsilane in the presence of ZSM-5 (Si/Al=30) as a catalyst at 350 degrees C-400 degrees C. Characterization of synthesized polycarbosilane was performed with Si-29 Solid NMR, FT-IR, and GPC analysis. Number average of molecular weight (M-n) of the polycarbosilane was ranged from 350 to 2340.
