## Abstract The supermolecular structure of cellulose acetate membrane casting solutions was determined by measuring their rheological behavior. The method was applied to both clear and turbid casting solutions. The resulting data on activation energy of viscous flow are shown to depend on the cell

This paper develops an experimental protocol for the characterisation of a concentrated cellulose acetate solution using a viscoelastic integral constitutive equation. Rheological parameters are obtained from both a Rheometrics RDSII spectrometer and a newly developed Multipass Rheometer (MPR). Reas
## Abstract GPC chromatograms of cellulose acetate made from wood pulp customarily show a shoulder or small separate peak at the high end of the DP distribution. Material isolated from this βprehumpβ area is considerably enriched in mannose and xylose, and the size of the prehump in acetates from d
