Summary

Carborane-hybridized silicon polymers were synthesized from the hydrosilylation reaction between diethynylbenzene-silylene polymers with reactive vinyl side groups and 1,7–bis(dimethylsilyl)carborane and 1,7–bis(diphenyIsilyl)carborane. Precise NMR spectroscopic studies show that the structures of these polymeres were quite complicated: unreacted vinyl groups and pendant carborane substitution exist along with crosslinked carborane. These polymers show plastic moldability. Thermal treatment of the hybrid polymers gives excellent stability in both thermal and mechanical properties of the polymers. Their unreacted moieties seem to act as crosslinkable thermosetting features to make these polymers more stable.
