Annotation	Vapour–liquid equilibria (VLE) were determined in the polystyrene + toluene system under isothermal conditions at 363.15, 373.15, and 383.15 K using an improved all-glass microebulliometer with circulation of the liquid phase for the dynamic measurement of total pressure over liquid mixtures. The experimental data were correlated using the UNIQUAC-free volume model. Additionally, the applicability of three known predictive models was tested. It was found that both the GC-Flory equation of state and the UNIFAC-vdW-FV model provide better prediction of VLE than the Entropic-FV model, which very slightly underestimates the experimental data for the system studied.
