The relative magnitudes of specific interactions are compared by setting up competitive equilibria in mixed solvent systems. The positions of the equilibria are determined spectroscopically by resolving the overlapping absorptions of the two solvation states. This technique is applied to the study of interactions between polyesters (or model compounds) and a variety of solvents which mimic possible interacting centers in halogenated polymers. Using the same technique of resolving overlapping bands, it is also demonstrated that in a miscible blend of polycaprolactone and Phenox (a polyhydroxyether of bisphenol A) only a relatively small proportion of the carbonyl groups of polycaprolactone are involved in specific interactions with the Phenoxy.
