Some thermodynamic quantities were obtained for the interactions of poly [2-(3-phenyl -3- methylcyclobutyl)-2-hydroxyethyl methacrylate-co-methacrylic acid] Poly (PCHEMA-co-MA) with alcohols, ketones, acetates, aromatics and n-alkanes by inverse gas chromatography in the temperature range of 150-180oC. The specific retention volumes, Vgo, weight fraction activity coefficients of solute probes at infinite dilution, W1\infty and Flory-Huggins thermodynamic interaction parameters, c12\infty between polymers and solvents were determined. The partial molar free energy, DG1\infty , the partial molar heat of mixing, DH1\infty , at infinite dilution and the solubility parameters of the polymer, d2 , were calculated. The copolymer was characterized by 1 H-NMR, FT-IR and DSC analyses
