PHOTOPOLYMERIZATION OF MMA INITIATED BY CYANINE DYE AND HEXAARYLBIIMIDAZ0LE*

Received Date: 22 April 1997

The photoinitiating system composed of 1-ethyl-3'-methylthiacyanine bro-mide (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 beused to initiate the polymerization of methyl methacrylate (MMA). The kinetic study wascarried out in trichloromathane solution at 30℃ by using dilatometry. The relation be-tween the polymerization rate and the concentrations of C-I, o-Cl-HABI, MTA and MMA was studied.
