Measurement and Correlation for the Vapor-liquid Equilibria of Polymer Solutions

Vapor liquid equilibrium (VLE) data of six single solvent/polymer systems (ben zene polystyrene (PS), toluene PS, benzene poly (methyl methacrylate) (PMMA), toluene PMMA, benzene poly(vinyl acetate)(PVAc) and toluene PVAc) at 308.15K have been measured by static vapor absorption method. The experimental results of chain fluid mixtures were correlated by UNIQUAC model and Liu and Hu's equat ion of state.
