| 英文摘要 | A new poly(methylsilane-carbosilane) (PMSCS) for silicon carbide precursor was synthesized by Wurtz-type copolycondensation of methyldichlorosilane (MeHSiCl2) with chloromethyldichloromethylsilane (ClCH2MeSiCl2) and terminated with vinylmagnesium chloride (ViMgCl). The use of insufficient sodium made the reaction more economic and safe. By changing the ratios of two monomers and the end-block agent, the properties of the obtained PMSCS and the C/Si ratio of its derived ceramic could be tuned. Upon pyrolysis at 1000 degrees C under argon, silicon carbide with nearly stoichiometric C/Si ratio and low oxygen content was obtained in 64% of ceramic yield. PMSCS showed high potential as an economical SiC ceramic precursor for the fabrication of SiC matrix, coating, and adhesives. (c) 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46610. |
