Polysilylenes, the linear silicon-silicon bonded polymers, have several interesting properties and are a subject of current intense investigations. Polysilylenes are prepared mostly by the Wurtz-type coupling reactions of dichlorodialkylsilanes which, however, have several difficulties such as the poor control of structure, molecular weight, and polydispersity. The yields of polymers are also usually low. In this paper, we will describe an entirely novel method of preparing polysilylenes based on anionic polymerization of masked disilenes.
