Abstract
Real-time FTIR-ATR spectroscopy was used to study the kinetics of photopoly merization reactions induced by monochromatic UV light. Various photoinitia tors with a broad range of extinction coefficients were tested for their ef ficiency to start the curing reaction of a diacrylate on irradiation at 313 or 222 nm. The effect of the absorption and initiation properties of the p hotoinitiators on the polymerization rate was analyzed. At 222 nm, the acry late was found to polymerize even without photoinitiator.
