摘要：
The mechanical, sorption, and permselective properties of membranes based on chitosan and chitosan complexes with carboxymethylchitin were studied as dependent on the polymer structure and its changes caused by water-temperature treatment. It was shown that the selectivity of chitosan films in the pervaporation of water-isopropanol mixtures increases with an increase in the degree of the polymer deacetylation, while the selectivity of films based on chitosan complexes with carboxymethylchitin enhances as their composition approaches stoichiometric and as a result. of the water-temperature treatment.
