Characterization of cellulose acetates containing microgel particles by the light scatter method

Abstract The Lange and Guinier methods have been used to determine the weight fraction of the microgel and the molecular parameters of the microgel and the molecular-disperse polymer in cellulose acetate solutions. The microgel particles in solvents of different thermodynamic quality significantly influence light scatter and as a consequence the mean square radii of inertia and the MW of cellulose acetates.
