Abstract

The activity of water In solutions of poly(ethylene glycols) (PEGs, molecular weights 200, 600, 1500, 6000) was measured over a wide range of weight fractions at 293.1, 313.1, and 333.1 K. The data were obtained by an isoplestic method. A comparison between the measured activities and predicted values by the UNIFAC method gives a good agreement for PEG 200 solutions only.
