摘要：

The reductive coupling of halogenated oligosilanes with potassium-graphite leads to novel polysilynes and branched polysilanes. The ratio of quarternary silicon atoms, monoorganosilyl- and diorganosilylgroups in the polymers can be modified by variation in the structure of the starting materials. Tn this way the properties of the preceramic polymers (molecular weights, solubility, content of carbon, degree of cross-linking) are influenced. The compounds are characterized by Si-29 NMR spectroscopy.
