Abstract
AbstractGas‐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.
