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.
硅烯（Me(3)Si）(2)Si=Ad发生聚合反应，生成一种具有不寻常的Si-Si-C重复主链的聚碳硅烷，而非烯烃自由基聚合预期的Si-C或Si-Si-C-C单元。通过凝胶渗透色谱法（GPC）、电子顺磁共振（EPR）、核磁共振光谱法以及捕获实验研究了聚合物结构和聚合机理（见示意图）。
