Abstract

In this study, an inverse gas chromatography (IGC) study of thermodynamic interactions of a chalcone modified poly (styrene) based polymer (PVBC-DMAC) with some solvents was presented. For this purpose, the retention data of carefully selected polar and non-polar solvents on PVBC-DMAC was obtained by IGC instrument at temperatures between 358.2 K and 383.2 K. Then, the polymer-solvent interaction parameters for Flory-Huggins theory, x12 and the equation of state theory, x12 , the effective exchange energy parameters, Xeff, the weight fraction activity coefficient, Ω1, and also the partial molar heat of mixing at infinite dilution of solvent, ∆H̅1, the molar heat of vaporization of solvent, ∆Hv, and the partial molar heat of sorption of s solvent, ∆H1 were calculated. The obtained results were discussed.
