Abstract
The methods of dilatometry and pulse photolysis have been used to study the photopolymerization of methyl methacrylate in benzene initiated by benzophenones in presence of amines. The effect of various factors on the rate of photopolymerization has been studied: substituent in benzophenone, the structure of the amine, the concentrations of methyl methacrylate and benzophenones and the intensity of light. A kinetic scheme of the mechanism and the experimentally obtained equations for the rate of photopolymerization are presented. It is shown that the influence of the substituent detected in the benzophenone molecule on the rate of photopolymerization of methyl methacrylate is manifest not in the photochemical stage.
