Some thermodynamic quantities were obtained for the interactions of poly (p-chlorostyrene) with n-pentane, n-hexane, n-heptane, benzene, toluene, isopropylbenzene and n-propylbenzene by the inverse gas chromatography method in the temperature range 150-170°C. The specific retention volumes ( V~g ), weight fraction activity coefficients of solute probes at infinite dilution (l'~), Flory-Huggins thermodynamic interaction parameters (X ~2 ), interaction parameters based on hard-core volumes (Z*2), effective exchange interaction parameters (X12) of the equation of state theory, between polymer and solutes are given. The molar enthalpy of sorption (A/4s), the partial molar heat of mixing at infinite dilution (A/7~:) and the solubility parameter of polymer (32) were also calculated.
