| Abstract: | Photopolymerization of methyl methacrylate was studied in the presence of the system of the tetraphenylporphine–iron(III) complex, free amine, and carbon tetrachloride at 0°C in methanol solution. It was found that the activity of the complex for polymerization does not depend upon the structure of the free amines added. The effect of the polymeric amines on the polymerization was also examined. The photochemical reaction process among the iron(III) complex, amine, and carbon tetrachloride was followed also under similar conditions by ultraviolet and visible spectroscopy. The scheme for the initiation species presented is supported by the results on the posteffect of the photopolymerization. |
