The free-volume theory of transport can be used to provide satisfactory descriptions of the temperature and concentration dependences of mutual and solvent self-diffusion coefficients in concentrated polymer solutions. The purpose of this article is to review data and to determine if the nature of this motion for a particular solvent is dependent on the characteristics of the polymer in which the solvent is undergoing the self-diffusion process. The theoretical basis for predicting size effects is presented and the available diffusion data for studying the effect of solvent size are discussed and interpreted.
