Values of the polymer/solvent interaction energy parameter were obtained within the Flory and Fujisawa-Hamada-Nakajima (FHN) corresponding states frameworks for the system carbon tetrachloride/poly(vinyl methyl ether). The FHN theory follows more closely the free-volume variation with temperature and accordingly, one is better able to correct for these free volume effects, obtaining a polymer/solvent interaction energy parameter independent of temperature. The scaling is also such, with FHN, that it results in lower, i.e. more negative, interaction energy parameters.
