Abstract

Abstract: The photopolymerization kinetics of combination photoinitiator systems which were composed by 2,2',5-tris(2-fluorophenyl)-4-(3,4-dimethoxypheny)- 4',5'-diphenyl-1,1'-biimdazole(WJ-HABI), photosensitizer N, N-bis(diethylamino) benzophenone (EMK) and hydrogen donors N-pheylglycine(NPG) were investigated by Real-time Infrared(RT-IR) spectroscopy. The different initiator concentrations, the different compositions of photoinitiator systems, light intensity and different functional monomers on the polymerization were studied. The results indicated that with the increase of initiator concentration and light intensity, the double bond conversion and the polymerization rate increased.

Key words: photopolymerization kinetics, photoinitiator, photosensitizer, hydrogen donors, RT-IR
