Resumo: - A group contribution equation of state recently proposed by the authors is used to calculate the activity of solvents in polymer+solvent solutions. The model is based on the generalized van der Waals theory and combines the Staverman-Guggenheim combinatorial term with an attractive lattice gas expression. The results show that the equation correlates the properties of pure solvents and polymers accurately. Furthermore, the equation satisfactorily represents the vapor-liquid equilibrium of solutions containing polymer and solvents of different polarities.
