Notes:
The Hildebrand solubility parameter δ, the Flory-Huggins interaction parameter χ, dilute-solution viscosities, apparent melting temperatures, and the equilibrium swelling of poly(vinyl chloride) (PVC) granules in plasticizer are compared as methods for assessing the degree of PVC-plasticizer interaction. Results from the empirical methods agree well with each other, but not with δ or χ. A quantitative activity parameter α, derived from χ, correlates well with all results other than δ values. A relative order of plasticizer solvent power has been established for nine plasticizers of widely differing structures and activities.
