Abstract

Size-exclusion chromatography of carbanilated cellulose of polystyrene-divinylbenzene packing has been used to determine the molecular weight distribution of the polymer with tetrahydrofuran as the eluent. The reproducibility and the accuracy of the method is discussed in this paper with reference to depolymerized organosolvent-treated celluloses. A comparison between the results obtained from the universal calibration approach and the viscosity-average degree of polymerization, derived from the determination of the intrinsic viscosity in cupriethylene diamine solutions, is presented
