摘要：

The cationic polymerization of cyclohexene oxide (CHO) is initiated upon u.v. irradiation (lambda(inc) > 350 nm) of dichloromethane solutions containing N-ethoxy-2-methyl pyridinium hexafluorophosphate (EMP+ PF6-) and poly(methyl phenyl silane) or poly(dimethyl dephenyl silane). A feasible initiation mechanism involves the photogeneration of silylene biradicals and silyl radicals by extrusion and main-chain scission of the polysilanes, respectively. Oxidation of these radicals by EMP+ ions yields reactive cations capable of initiating the polymerization of CHO.
