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.
