STUDY OF THE PHOTOLYSIS OF SULFONIUM SALT S, CATIONIC PHOTOINITIATORS

Arylonium salts allowed the development of cationic photopolymerizatio n. A number of reports abo ut the photolysis of triarylsulfonium salts can now be found in the literature. These works deal with salt photof ragmentation kinetics, the visualization of the photolysis process by real time pH mesurements and with the acid photoliberation kinetics by potentiometric titrations.
