Abstract: The synthesis of poly(diphenylsilylene-co-methylene) of the general composition [SiPh2(CH2)1,1]x was afforded by the reaction of diphenyldichlorosilane and dibromomethane with sodium. The product obtained was characterized by elemental analysis and by 1H, 13C, 29Si NMR, IR spectroscopy, and gel permeation chromatography. The pyrolysis process of the oligomeric poly(diphenylsilylene-co-methylene) was investigated up to 1700 °C, and the gaseous, liquid, and viscous decomposition products were mainly identified by GC-MS coupling method. The ceramic residues were determined and analyzed, and the state of β-SiC crystallization was examined by XRD analysis.
