Abstract: 
Regularities of kinetics of photoinitiated copolymerization till high conversions in the systems of monofunctional methacrylate comonomers (hydroxyethyl methacrylate (HEMA), glycidyl methacrylate (GMA)) have been investigated by laser interferometry in a wide range of experimental factors (molar ratio of comonomers, photoinitiator concentration, intensity of UV-irradiation). Kinetic model of photoinitiated copolymerization of methacrylates till high conversions has been proposed on the basis of microheterogeneity conception of the polymerization process.
