Photopolymerization Reactions For Imaging Applications : Role Of Multicomponent Photoinitiating Systems

H. Obeid

The role of multicomponent photoinitiating systems - based on various combinations of a bis imidazole derivative, an aminobenzophenone, an iodonium salt and an amine - in the photopolymerization of an acrylate formulation under light irradiation at 365 nm, has been investigated.

Role of Dimer Radical Cation and Radical in Polymerisation of 2,3-Dihydrofuran

Formation of distonic dimer radical cations, characterised by spatially separated charge and radical site, was observed in our previous studies with irradiated frozen Freon matrices containing vinyl ethers, 2,3-dihydrofuran (2,3-DHF) 2,3] and 2,3-dihydropyran 4J.

Photochemistry of Quaternary Ammonium Thiocyanates and Their Behavior as Photobase Generators

Prof. Dr. Tsunooka

Photochemical reactions of quaternary ammonium salts (QASs) bearing phenacyl groups and
thiocyanate anions were investigated, and their performance as a catalyst for curing of epoxides was demonstrated. Upon UV-irradiation, QASs having thiocyanate anions generated amines, which
