Abstract
The behaviour of some amine antioxidants and antiozonants and of some model substances (phenols, aromatic hydrocarbons, and amines) during gel permeation chromatography are reported. The investigation was carried out on a polystyrene gel chromatograph with tetrahydrofuran as the solvent, at 30°. The elution volumes were found and the molar volumes determined by calibration with standard hydrocarbons. The behaviour of the amine compounds is characterized with respect to the important structural factors affecting their elution volumes. The gel permeation chromatographic analysis of amine stabilizers in polyolefins and rubbers can be combined with other methods for qualitative and quantitative determination.
