Özet

Vinyl cation-based initiating system for cationic polymerization of cyclohexene oxide (CHO) has been developed by using photochemical free radical sources in conjuction with diphenyl acetylene (DPA) and triphenyl sulphonium hexafluorophosphate. An initiation mechanism involving the formation of substituted vinyl radical and subsequent oxidation to the corresponding cations is proposed.
