Athabasca asphaltene has been separated according to molecular weight on Bio-Beads SX-1 gel. The number-average molecular weights of the five arbitrary fractions obtained by this fractionation range from 1200to 17000. Thechemical, spectral and thermal propertiesof thefractionsareall similar but thei
