Vinyl acetate (a polar compound) has become a key ingredient in many industrial and consumer products. However, very little is known about its thermodynamic properties. This article presents a simple modification of Wu and Stiel's (1985) method (originally) developed for predicting thermodynamic properties of polar compounds up to P r = (10) for extending its range of applicability to very high pressures of the order of P r = 80. The predictions show good agreement with the experimental data for specific volume in the case of vinyl acetate, and specific volume, enthalpy and entropy for mixtures of ethylene and vinyl acetate for compositions up to 50 wt. % of vinyl acetate. Further validation for other polar systems would determine if this method is applicable to polar compounds in general.
