Prediction of polymer-solute thermodynamic parametersχ;12 and Ω;1∞; from inverse gas chromatography data. Application to poly(propylene oxide)-solute system

The solvation equation has been applied to the solubility of 13 probes in poly(propylene oxide). It has been shown that log Vg0 values can be predicted with reasonable precision using this equation, while the results are not so good for predicting thermodynamic parameters. The high values found when applying regression analysis to the independent parameter c, indicates that parameters exist with a marked effect on retention but not included in the equation.
