ESTIMATION OF THERMODYNAMIC PARAMETERS OF POLYSTYRENE-N-HYDROCARBONS SYSTEMS USING INVERSE GAS-CHROMATOGRAPHY

Abstract

Thermodynamic parameters like partial molar free energy, Flory-Huggins interaction parameter, weight fraction activity coefficient and molar heats of polystyrene- n}hydrocarbons systems were determined by using inverse gas chromatography technique. The results obtained showed similarity with that of polymer-non solvent systems.
