Abstract
Solvent sorption equilibrium data of binary solvent-polymer systems were measured with a vacuum electro-microbalance equilibrium cell. Tested solvents were benzene, n-pentane, cyclohexane, n-hexane, water and methanol. Polymers tested were poly(dimethylsiloxane), poly(iso-butylene), poly(propylene oxide) and poly(vinyl alcohol). Data obtained in the present study, together with existing literature data, were correlated by two gE-models, such as UNIQUAC and the Flory-Huggins model, and four equations of state which stem from the lattice fluid theory, such as models proposed by Flory, Sanchez and Lacombe, Panayiotou and Vera, and the NLF model proposed recently by the present authors. For each solvent-polymer system, the provided models give a quantitative correlation. The advantages and drawbacks of the gE-model and equation of state approaches are also discussed.
