Correlation between the change in Coulomb interaction energy ΔECoul and change in the number of H-bonds (ΔNHB) in blends of 40 wt % FLA with PVP, EEC, PSA, and PAA (from higher to lower values of ΔNHB). Numbers are the differences between the quantities in the mixtures and of the equivalent numbers of molecules in the pure phases.
