Abstract: The polymerizable amine ethylene glycol 3-morpholine-propionate methacrylate was used as coinitiatos for benzophenone(BP),4-(4-methylbenzisulfide-phenyl)phenyl ketone(BMS),4-chloro-benzophenone(CBP),4-chloromethyl benzophenone(CMBP),4-hydroxymethyl benzophenone(HMBP) photoinitiator system.The photopolymerization kinetics of 1,6-Hexanediol Diacrylate(HDDA) was investigated with Photo-DSC.The result indicated that the structure of diaryl ketone and their mass ratio played an important role on kinetics of photopolymerization rate and monomer conversion,and increasing light intensity and temperature could lead to the increase of photopolymerization rate and the final conversion.The activation energy(Ea) of photopolymerization of HDDA initiated by EGMPM/BP had been calculated.

Key words: polymerizable amine, diarylketone, photopolymerization kinetics, Photo-DSC
