Abstract

AbstractVapour pressures in concentrated solutions of poly(ethylene glycol)s (M̄n = 300, 400, 600, 1000, 1500, 2000, 4000 and 6000 g/mol) in ethylbenzene have been measured in the temperature range of 303.15 K to 403.15 K and segment‐molar excess Gibbs energies \documentclass{article}\pagestyle{empty}\begin{document}$\overline{\overline G} ^E $\end{document} have been calculated. Results are discussed on the basis of free volume concepts and the UNIFAC‐model.
