Kinetic studies were carried out on the polymerization of MMA photo-initiated by benzophenone/triethylamine/oxygen(BP/TEA/O2) system.Experimental results shown that the rate of polymerization is directly proportional to [BP]0.25 [TEA]0.25 [MMA] [O2] and [IO]0.5. Some deviation from this relationship has been found in ease of too high concentrations of photosensitized initiation syrstem.This may be at- tributed to the strong enhancing cage deactivation and extinction of the intermediate products.The accelerating effect of oxygen in this system resulted an increase in the rate of polymerization to 1.4 times and a quantum yield to 4.4×102.
