Abstract The photoinitiated cationic polymerization of cyclohexene oxide with N ‐phenacyl‐ N,N ‐dimethylanilinium hexafluoroantimonate (PDA + SbF 6 – ) and a polynuclear aromatic compound, such as perylene, anthracene or phenothiazine, or an aromatic carbonyl compound, such as benzophenone or thioxanthone, was studied at λ inc > 340 nm. All the aromatic sensitizers except benzophenone and thioxanthone are effective in initiating the polymerization at wavelengths where PDA + SbF 6 – is transparent. An initiation mechanism is proposed that involves electron transfer from the excited sensitizer to PDA + SbF 6 – .
