Abstract
The pyrolysis of poly(methylchlorosilanes) prepared by catalytic dispr oportionation of disilanes leads to the formation of silicon carbide. The first step of the process is a polysilane to polycarbosilane trans formation, which occurs with the insertion of methylene groups into Si -Si bonds. For the first time, this transformation was studied by C-13 MAS-NMR, using cross polarization (CP) and Inversion Recovery Cross P olarization (IRCP) techniques.
