The kinetics of photopolymerization of oligodimethacrylate and diethylene glycol diacrylate at the wide range of photoinitiator concentration was investigated. We found the dependences between the intensity of the UV-irradiation and of the thickness of photocomposition on layer and kinetic parameters. Experimental date were compared with kinetic model of the photoinitial three-dimensional polymerization. It was determined that kinetic model allows us to describe the process of three-dimensional polymerization in the whole range of conversion. Molar extinction coefficient of photoinitiator and quantum yield of the decomposition, rate constants of homo (k1)- and heterophase (k2) process were estimated. It was determined that k1 is influenced by the dimethacrylate properties and k2 is a constant value for the whole investigated systems. |
