Abstract
Precise diffusion coefficient measurements have been performed using c hronoamperometry in highly concentrated ionically conducting polymer s olutions made with DMF as the solvant (solid polymer gels). The D vari ation with the temperature lets appear a transition temperature which is characteristic of the system. Interpretation of the results in term s of a free volume law is proposed and agrees well with the experiment al D variation and allows to determine some of the parameters for a gi ven gel.
