The density and speed of sound of the solutions of poly(propylene glycol) 400, in ethanol and 2-propanol at T ) (288.15 to 328.15) K, and dynamic viscosity of these solutions at T ) (298.15 to 328.15) K have been measured experimentally over the entire range of compositions and atmospheric pressure. From these experimental data, the excess molar volume, V m E , excess molar isentropic compression, κ E s,m , and deviation of logarithm of viscosity, ∆ ln η, have been determined for each composition. V m E , κ E s,m , and viscosity data have been adequately fitted to the Redlich-Kister and NRTL models.

“…PPG is used in many formulations for polyurethanes. It is used as a rheology modifier; 1 in solid tires, automobile seats, 2 foams, 3 membranes; 4 and in talc separation from talc-carbonate ore. 5 An understanding of the thermodynamics of the polymer solutions is important in practical applications such as polymerizations, devolatilization, and incorporation of plasticizers and other additives. Diffusion phenomena in polymer melts and solutions are strongly affected by nonideal solution behavior since the chemical potential rather than the concentration provides the driving force for diffusion.…”

The activities of ethanol and 2-propanol in poly(propylene glycol) 400 (PPG 400) solutions have been measured by the improved isopiestic method at T = (298.15 to 328.15) K. The original equation of Flory−Huggins and the modified Flory−Huggins equation with concentration-dependent interaction parameters have been used for the correlation of the experimental solvent activity data. It was found that for the studied systems at any mass fraction, as the temperature is increased the solvent activities and Flory parameters are both decreased, indicating an increase of interaction between polymer and solvents as the temperature is increased. The reliability of the two local composition models, NRTL and Wilson, was also assessed by fitting the experimental activity data to these models. All of these models satisfactorily present the obtained experimental activity data at different temperatures.
