This paper is another one in the series of continuing research of vapour–liquid equilibria (VLE) measurements in polymer + solvent systems. VLE were determined in the polystyrene + 2-butanone system under isothermal conditions at 333.15, 343.15, and 353.15 K in order to complete the previous studies on the polystyrene + toluene and poly(methyl methacrylate) + 2-butanone systems including earlier investigations. Measurements were carried out with use of an all-glass microebulliometer with circulation of the liquid phase for the dynamic measurement of total pressure over liquid solutions. The experimental data were correlated using the UNIQUAC-FV model and the applicability of known predictive models was tested. It was found that prediction of VLE using the GC-Flory equation of state, the UNIFAC-vdw-FV and the Entropic-FV model are of the same quality.
