Synthesis and Properties of Interpolymer Complexes Based on Chitosan and Sulfated Arabinogalactan

Interpolymer complexes based on chitosan and arabinogalactan with a different degree of sulfation (7.7–40.8%) stable for 30 days are synthesized. The resulting complexes are characterized by scanning electron microscopy, IR spectroscopy, dynamic light scattering, and ζ-potential electrophoretic measurements. The main mechanism of complex formation is considered in terms of the electrostatic bonding of polyions. New complexes show promise as biosorbents and drug delivery systems.
