Abstract
Flow birefrigence and intrinsic viscosity of carboxymethyl cellulose i n cadoxene solutions with different water, alkali, and NaCl content we re studied. It was found that the constitution and nature of the solve nt used significantly affect the conformational characteristics of mol ecules of substituted cellulose. Variations in the ionic strength of t he solvent (or in the cadmium content in the mixed solvent) change the optical anisotropy of macromolecules and the extent of their equilibr ium rigidity.
