Abstract : A method for investigating the molecular weight distribution of cellulosic materials has been used to study some regenerated cellulose samples. The procedure involves gel filtration chromatography of cadoxen solutions on an agarose gel. Elution diagrams reflecting the molecular weight distribution of e.g. HWM- and polynosic fibres are presented. Some of the samples which had approximately the same degree of polymerisation gave rather different elution diagrams. Products of similar mechanical properties may also be assumed to have varying DP-values and polydispersities. (Author)
