The film-casting solution consisted of a mixture of cellulose acetate, acetone, and aqueous magnesium perchlorate [Mg(C10&: HzO = I :8.5], designated as polymer P, solvent S, and nonsolvent N, respectively. Using the composition P:S:N = 17:69.2: 13.8 as reference, films were obtained from 19 differe
## 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
