Abstract
The mechanical, sorption, and permselective properties of membranes ba sed on chitosan and chitosan complexes with carboxymethylchitin were s tudied as dependent on the polymer structure and its changes caused by water-temperature treatment. It was shown that the selectivity of chi tosan films in the pervaporation of water-isopropanol mixtures increas es with an increase in the degree of the polymer deacetylation, while the selectivity of films based on chitosan complexes with carboxymethy lchitin enhances as their composition approaches stoichiometric and as a result. of the water-temperature treatment.
