摘要：

The polymerization of methyl methacrylate (MMA), ethyl acrylate (EA) , styrene (St) and 2-vinyl pyridine (VP) is initiated upon irradiation at lambda>350 nm of dichloromethane solutions containing N-ethoxy-2-methylpyridinium hexafluorophosphate (EMP+PF6-) and anthracene or thioxanthone. Initiation mechanisms involving the formation of ethoxyl radicals during the decomposition of EMP+ ions via electron transfer are proposed.
