title: Radical polymerization of the silene (Me3Si)2Si=CR2 by hydrogen transfer from a trimethylsilyl group.
abstract: The silene (Me(3)Si)(2)Si=Ad is polymerized to produce a polycarbosilane with an unusual Si-Si-C repeating backbone, rather than the Si-C or Si-Si-C-C units expected for olefinic radical polymerization. The polymer structure and the polymerization mechanism (see scheme) were studied by GPC, EPR, and NMR spectroscopy and by trapping experiments.
