摘要：

A theory is developed for predicting the solvent self-diffusion coefficient in a crosslinked, amorphous polymer. The theory is based on a modification of the free-volume theory of transport for the presence of crosslinks in the polymer. The general predictions of the theory for the variations of the self-diffusion coefficient with temperature, concentration, degree of crosslinking, and solvent size are compared with general experimental trends.
