摘要：

A model was developed to describe to describe the kinetics and physical aging during photopolymerizations of diacrylates and dimethacrylares that form highly cross-linked networks. The model incorporates the strong coupling between the volume relaxation and the kinetics observed in these reactions. Model predictions are presented for the reaction kinetics, volume relaxation, radical concentration, and attainment of a maximum conversion as a function of light intensity and relaxation time of the polymer. These results agree qualitatively with experimental observations for photopolymerizations of diacrylates and dimethacrylates. The invalidity of the pseudo-steady-state hypothesis for these reactions is also pointed out.
