In this study, we determined the thermodynamic properties [such as the adsorption enthalpy, ΔH a , the sorption enthalpy, , sorption free energy, , sorption entropy, , the partial molar free energy, , and the partial molar heat of mixing ] at infinite dilution for the interactions of poly[(2-phenyl-1,3-dioxolane-4-yl) methyl methacrylate-co-glycidyl methacrylate] poly (PDMMA-co-GMA) with alcohols and n-alkanes by the inverse gas chromatography method in the temperature range of 343-463K. According to the specific retention volumes ( ), the weight fraction activity coefficients of solute probes at infinite dilution, Ω 1 ∞ , and Flory-Huggins interaction parameters (χ ∞ 12 ) between poly (PDMMA-co-GMA)-solvents were determined in 423-463K. According to and , selected alcohols and n-alkanes were found to be nonsolvent for poly (PDMMA-co-GMA) between 423 and 463K. Also, the solubility parameters, δ 2 , of poly (PDMMA-co-GMA) were found to be 22.15 (J cm −3 ) 0.5 and 25.50 (J cm −3 ) 0.5 from slope and intercept of [( /RT) −  /V 1 ) = (2δ 2 /RT)δ 1  −  /RT equation, at 443K, respectively. The glass transition temperature (T g ) of the poly (PDMMA-co-GMA) was found to be 370 and 367K, respectively, by inverse gas chromatography and differential scanning colorimetry (DSC) techniques.
