Densities, Viscosities, Refractive Indices, and Heat Capacities of Poly(ethylene glycol-ran-propylene glycol) + Esters of Carbonic Acid at (293.15 and 313.15) ° K and at Atmospheric Pressure

Densities, Á, dynamic viscosities, ·, refractive indexes, nD, and heat capacities, Cp, for the binary mixts. contg. poly(ethylene glycol-ran-polypropylene glycol) + esters of carbonic acid were detd. at (293.15 and 313.15) K and at atm. pressure using an Anton Paar d. meter, a Schott-Gerate AVS viscometer, an Abbe refractometer, and a Perkin-Elmer differential scanning calorimeter. Vol. variations, ”V, during mixing and deviations of the dynamic viscosities, ”·, were obtained at these temps. and are neg. for all mixts. Exptl. data were fitted to the Redlich-Kister equation, and the adjustable parameters and the std. deviations between exptl. and calcd. values were estd.
