Abstract
Polyphenylsilyne and branched copolysilanes have been prepared via red uctive coupling of the corresponding organochlorosilanes with potassiu m-graphite. Reaction of these polymers with trifluoromethanesulfonic a cid lead to triflate substituted polymers. These compounds are modifie d by following reactions with nucleophiles, LiAlH4, or C8K. The simple syntheses allow variation of the properties of the preceramic polymer s (molecular weights, solubility, content of carbon, functional groups ). The polymers are characterized by Si-29 NMR spectroscopy.
