GEL PERMEATION CHROMATOGRAPHY OF ASPHALT AND THE CHARACTERIZATION OF ITS FRACTIONS IN TERMS OF MOLECULAR AND UNIT SHEET WEIGHTS

Asphalt obtained from a refinery in Montreal was dissolved in toluene then fractionated in a preparative gel permeation chromatography (prep. -GPC). Twenty-three fractions differing widely in molecular weights were collected and characterized by analytical GPC, viscometry, vapor pressure osmometry (VPO), element analyses, infrared spectroscopy (IR), and nuclear magnetic resonance spectroscopy (NMR). The GPC chromatograms of the fractions generally revealed narrow distributions indicating that their separation into different component groups has been reasonably well achieved.
