摘要：

Molar heat capacities, C,, densities, p, dynamic viscosities, eta, and refractive indices, no, for the binary mixtures poly(ethylene glycol) 200 and poly(ethylene glycol) 400 + 2-methyltetrahydrofuran (MTHF) were determined at (293.15, 303.15, and 313.15) K using a Perkin-Elmer differential scanning calorimeter, an Anton Paar density meter, a Schott-Gerate AVS unit, and an Abbe refractometer, respectively. Excess molar volumes, V-m(E), deviations of the dynamic viscosities, Delta eta, and deviations of the refractive indices, Delta R, were calculated at these temperatures. These properties were fitted to the Redlich-Kister equation.
