Notes:
Gas-liquid chromatography is used to measure polymer-solvent interactions in polymer solutions where the solvent is at infinite dilution. Experimental data are presented for 24 binary polymer-solvent systems in the temperature range 50° to 150°C. A simple relation exists between the experimental retention volume data and the infinite dilution volatility; this volatility can be used to calculate the solvent vapor pressure over the polymer solution up to about 0.1 weight fraction solvent. Using concepts from the Prigogine-Flory theory of polymer solutions, Flory-Huggins X parameters for some polymer-hydrocarbon systems were correlated with the hydrocarbon's normal boiling temperature.
