The silene (Me3Si)2SiAd is polymerized to produce a polycarbosilane with an unusual SiSiC repeating backbone, rather than the SiC or SiSiCC 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.
