The rheological behavior of acetate and succinimide of chitosan in mixed solvents was investigated. It is shown that the replacement of a part of the solvent by two- or three-atom alcohols is accompanied by an increase in the relative and dynamic viscosity of the succinimide chitosan solution, an earlier formation of the net of links, a transition from viscoelastic systems to elastoviscous ones at lower polymer concentration values and an increase in the relaxation time.
