The compatibility of suspension poly(vinylchloride) [PVC] with twelve different plasticizers was determined using calculated compatibility predictors, as well as actual measurements of compatibility. Solubility parameters were capable of classifying plasticizers of a given family in terms of their compatibility with PVC, but were not useful for comparing plasticizers from different families. A polarity parameter, the product of the molar mass of the plasticizer and its polarity ratio, was found to be a useful predictor of activity for monomeric plasticizers.
