Thermal and photoinduced cationic polymerizations reveal catalytic activity in various allylic salts, suggesting effective initiation methods.
Thermally and photoinduced cationic polymerizations of cyclohexene oxide (CHO) initiated by allylthiophenium, allylpyridinium, allylalkoxypyridinium and allylphosphonium salts with non-nucleophilic counter anion hexafluoroantimonate and with an ethoxy carbonyl substituent at the allylic moiety were studied. The catalytic activities in the polymerization were examined and compared to those measured in both the absence and presence of added radical initiators.
