Abstract
The photophysics and photochemistry of thiopyrylium salts have been in vestigated by UV-VIS absorption spectroscopy and nanosecond laser abso rption spectroscopy. The effect of substituents of the heterocycle on the photophysical properties was analysed. Dissociation of peroxidic c ompounds photosensitized by these salts was studied. The interaction w ith monomers and many other additives has also been investigated. A me chanism is proposed for the initiation of acrylic photopolymerization reactions.
