摘要：

Poly(vinylsilane), (H2SiC2H4)n, has been synthesized by a hydrosilylation route. Depending on the experimental conditions, the average molecular weight varies from 640 to 5500. The structure of these polymers, which was investigated by H-1, C-13, and Si-29 NMR spectroscopy, is explained on the basis of the two possible modes of addition in the hydrosilylation reaction. Pyrolysis of either low or high molecular weight polymers gives similar ceramic yields (32-40%), which are higher than for non-cross-linked poly-(silapropylene), (CH3SiHCH2)n. This result emphasizes the role of the latent SiH functions in the pyrolysis step.
