Abstract

The solubility and phase state of the sodium salt of cellulose acetate sulfate in water-ethanol, water-isopropanol, water-ethylene glycol, and water-glycerol mixtures were determined over a wide range of component concentrations. Viscometry was used to obtain the hydrodynamic parameters of dilute solutions of various salt forms of cellulose acetate sulfate such as the characteristic viscosity [eta], Huggins constant k(H), and crossover concentration c*. For the first time, an empirical criterion, [eta]k(H)c*, was suggested that could be used to predict the formation of the liquid crystalline state in concentrated solutions of cellulose derivatives.
