Abstract
Photograft copolymerization of methoxypolyethyleneglycol methacrylate (SM) and 2-(dimethylamino)ethyl methacrylate (DAEM) to poly(acrylonitrile) containing bromine atoms (PANBr) in dimethyl sulphoxide was carried out and the changes of concentration of SM and DAEM with time were measured by thin-layer chromatography. Also, the change of concentration of bromine atoms in PANBr during the photolysis of PANBr was measured spectrophotometrically to determine the overall quantum yield of the photolysis reaction.
Simulation of the photograft copolymerization was carried out by substituting the overall quantum yield and other kinetic parameters such as monomer reactivity ratios, polymerization rate constants and φ factor, which were obtained separately, into equations for the photopolymerization. Agreement between data obtained from experiment and from calculation was very good.
