Casting Solutions from cellulose acetate, cyanoethyl acetyl cellulose, hydroxypropyl acetyl cellulose and titanium cellulose acetate have been studied with IR and viscosity methods. McAllister equation and Huggins equation are used to describe the viscosity behavior of acetone-additive solutions and cellulose derivative-acetone-additive solutions, respectively. Phosphoric acid, formamide, npropanol and glycerine were used as additives. It is found that additives used showed a certain effect on the interaction among macromolecules of cellulose derivatives and on their morphological structures.
