Examination of the concentration dependence of TgTg of binary aqueous solutions

We present Differential Scanning Calorimetry (DSC) results of rapidly quenched samples of the aqueous solutions of glycerol, propylene glycol and ethylene glycol along with some of their oligomers over a wider concentration. We have critically examined the concentration dependence of glass transition temperature (Tg)(Tg) of these mixtures. Our results indicate that the Gordon–Taylor equation is not the correct description of the situation. The implication of this finding on the determination of TgTg of bulk water from the binary solution data, is discussed.
