Abstract

The UNIFAC group contribution method has been used to calculate the free energy of mixing versus composition curves for several polymer-plasticizer systems, including phthalates and stearates with poly(vinyl chloride). The solubility of the plasticizer has been calculated from the curves and compared with experimental results. Although the absolute values of the solubilities were underestimated, the relative solubilities amongst groups of compounds were predicted well, so that the method may be useful in the prediction of compatibility in these systems.
