Abstract
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-me thylpyridinium hexafluorophosphate (EMP+PF6-) and anthracene or thioxa nthone. Initiation mechanisms involving the formation of ethoxyl radic als during the decomposition of EMP+ ions via electron transfer are pr oposed.
