Abstract
The photopolymerizations of methyl methacrylate (MMA) with N-cetylpyridinium bromide (CPB) and N-cetylpyridinium chloride (CPC) were investigated in aqueous system. With CPB alone, photopolymerization did not proceed, but by the addition of a small quantity of CCl4, it was significantly accelerated. The rate of the photopolymerization of MMA with CPB in the presence of CCl4 showed a linear relationship with the square root of CPB concentration, but was little affected by the concentration of CCl4. With CPC MMA also photopolymerized in the presence of CCl4, and especially at more than a critical micelle concentration (CMC) of CPC, the time-conversion curve showed a characteristic feature of emulsion polymerization, where Rp was proportional to the 0.75 power of the fed quantity of CPC, but almost independent of CCl4 concentration. The above photopolymerizations with CPB and CPC in the presence of CCl4 were, however, remarkably accelerated by the addition of KBr.
