Abstract
The behavior of cellulose acetate was studied in over 30 solvents. It was found that the concentration C* at which the anisotropic phase appears, is dependent on the nature of the solvent. In strong or moderately strong acids, C* is linearly dependent on pK, that is, the stronger the acid the lower the concentration at which anisotropy makes its first appearance. In other solvents, C* is inversely dependent on the molar volume of the solvent.Keywords
