succinimide chitosan

Receiving Elastoviscous Systems on the Basis of Aqueous Solution of Acetate and Succinimide of Chitosan in the Presence of Polyhydric Alcohols

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.
