This project is a study of molecular diffusion in homogeneous                   polymer-solvent systems.  The main thrust of the work is an                     investigation of transport processes which occur when there is coupling         between molecular migration and polymer chain relaxation.  This                 coupling phenomenon results in "anomalous" diffusion effects which ave          excluded a fundamental understanding of many processes which involve            polymer-solvent interactions.  A newly developed oscillatory sorption           technique is utilized to study the coupling of diffusional transport            and relaxation which is unique to polymer-solvent systems.  This is the         only experimental technique available which permits an unambiguous              investigation of this phenomenon.  The experimental results are used to         formulate constitutive equations to describe diffusional fluxes taking          place under conditions where migration and polymer chain relaxation are         interacting.
