Abstract

Dinesh N. Vora and S. S. Dodwad

Viscosity of the binary mixtures of PEG 200 and PEG 400 with ethyl acetate as a function of temperature and composition were experimentally measured at 303, 313 and 323 K. Excess viscosity (ηE), excess Gibbs free energy of activation of flow (Δ G*E) and Grunberg and Nissan interaction parameter (d) have been calculated. The values hae been discussed in the light of specific interaction phenomena.
