摘要

The photoinitiating system composed of 1-ethyl-3'-methyl thiacyanine bromide (C-I), 2-chlorohexaarylbiimidazole (o-Cl-HABI) and 3-mercapto-4-methyl-4H-1, 2, 4-triazole (MTA), which act as sensitizer, initiator and hydrogen-donor respectively, can be used to initiate the polymerization of methyl methacrylate (MMA). The kinetic study was carried out in trichloromathane solution at 30℃ by using dilatometry. The relation between the polymerization rate and the concentrations of C-I, o-Cl-HABI, MTA and MMA was studied.
