Abstract

The ionization characteristics of polyelectrolyte complexes composed of dextran sulfate/chitosan (DS/CH) gels were analyzed. A theoretical model to estimate the net charge of DS/CH gels from the swelling equilibrium data was developed. The effect of complex formation on the dissociation constant of protonated amino groups of CH was discussed.
