摘要：

The free-volume theory for solvent self-diffusion in polymer-solvent systems is applied to rubbery mixtures at temperatures both above and below the polymer glass transition temperature. A new parameter evaluation scheme is introduced, and it is shown that the theory provides good predictions for the solvent self-diffusion coefficient over wide temperature and concentration ranges.
