Abstract : Fractions of poly(isobutyl methacrylate) were dissolved in tetrahydrofuran and run at 25C. Values of -Aw and -An were obtained. The molecular weight of most of the fractions had been obtained previously by light scattering measurements. From the values of -Aw and -An and the 'Q' factor, molecular weights were obtained that were completely erroneous. However, a correlation between -Aw and -Mw was determined. Without the previously determined information on molecular weight, it would have been impossible to determine this quantity from gel permeation chromatography alone. The molecular weight distribution was studied only briefly. (Author)
