Résumé : Summary. ‐ In this paper, dielectric constants and dielectric losses have been measured at various frequencies for solutions of Polyvinyl Chloride in mixtures of Tetrahydrofurane and normal Heptane. Previous conclusions have been confirmed. Moreover it has been shown that the precipitant has practically no influence on dipole moment, critical frequency, activation energy or entropy.
