Abstract

The thermodynamic and acid base properties of some polymeric materials such as polylactides used in many industrial applications were determined by using the inverse gas chromatography technique at infinite dilution. Retention volume of the injected organic probes into the chromatographic column containing the investigated polymer was obtained by using this powerful technique.
