On the basis of the microheterogenous model and taking into account the light gradient the kinetic equation of the three-dimensional photoinitiated polymerization of the polyfunctional oligomers in block is obtained. The prediction of models for the initial stage of the process and endless thin layer-are correlated with the experimental data of photopolymerization of the bifunctional oligoacrylate. obtained within the wide range of values of photoinitiator concentration, thickness of the composition layer and the intensity of the light falling on its surface. In all cases the data predicted by the model correlate with the experimental observations. The following parameters of the model are found: coefficient of the photoinitiator extinction, quantum yield of its decay, constants of the rates of homophase and heterophase polymerization process. The comparison of the calculated set of parameters and experimental kinetic curves shows, the satisfactory correspondence of the suggested model including the fluctuation dependence of the rate of three-dimensional polymerization caused by the microheterogenity of the process. |
