Abstract: The kinetics of photopolymerization of 4-acryloylbenzophenone (4-ABP) was studied by Real-time Infrared spectroscopy,which showed that 4-ABP was a very effective photoinitiator.When the photoinitiator and amine were used to initiate polymerization of acrylates,both rate of polymerization and final conversion increased and the induction period shortened with increase of amine concentration,4-ABP concentration and light intensity.For it is crosslinked in the cured film,the amount of extracted 4-ABP is much lower than that of BP.

Key words: polymerizable photoinitiator, photopolymerization, kinetics, extractability, RT-IR
