Vapor–liquid equilibria have been determined in the systems composed of polyacrylic acid with water by ebulliometric total pressure measurement method. Experiments have been carried out isothermally at 353.15, 363.15 and 373.15 K. The measured data were correlated with the UNIQUAC equation, and compared with data by Arce et al. measured using the different experimental technique at 303.15 K. Values predicted by two group contribution models, namely the Entropic–FV and the GC–Flory models are underestimated in comparison with experimental data.
