Abstract
The photochemical dissociation of different diazonium salts has been examined from the point of view of its quantum yield, its photosensitization and its ability to initiate the cationic polymerization of N-vinylcarbazole and the cross-linking of glycidyl methacrylate copolymers. These results are compared with recent data of the literature concerning diaryliodonium and triarylsulfonium salts. In the second part, the possibility of involving the photochemical dissociation of onium salts in a chain reaction is considered on the basis of experimental data, and the concept of electron-transfer reaction with organic free radicals is generalized.
