Specific Features of the Formation of Aqueous Nanodispersions of Interpolyelectrolyte Complexes based of Chitosan and Chitosan Succinamide

Resumo

Aqueous dispersion of particles of interpolyelectrolyte complexes based on chitosan hydrochloride and sodium salt of chitosan succinamide have been prepared and characterized. The size of the complex particles and the system stability are affected by the concentration of the polymers in the solution and the molar ratio of the components. In the studied disperse systems, steady aggregation of the particles has led to the precipitation of the insoluble complex, and the relative stability of the systems against aggregation has increased with the increase in the fraction of the lower-molecular component and concentration of the polymers in the solution.
