ABSTRACT

Densities, ?, dynamic viscosities, ?, refractive indices, nD, and heat capacities, Cp, for the binary mixtures containing poly(ethylene glycol-ran-polypropylene glycol) + esters of carbonic acid were determined at (293.15 and 313.15) K and at atmospheric pressure using an Anton Paar density meter, a Schott-Gerte AVS viscometer, an Abbe refractometer, and a Perkin-Elmer differential scanning calorimeter. Volume variations, ?V, during mixing and deviations of the dynamic viscosities, ??, were obtained at these temperatures and are negative for all mixtures. Experimental data were fitted to the Redlich-Kister equation, and the adjustable parameters and the standard deviations between experimental and calculated values were estimated.
