The features of the modification of acid-soluble chitosan by carbonyl-containing compounds in solution and by the method of surface modification of molded materials are investigated. The dependence of the rheological properties of polysaccharide solutions on the structure of the hydrocarbon radical of the modifier is established. The formed films based on iminochitosans, obtained by the interaction of the polymer with aldehydes in a solution of acetic acid, have lower surface, hydrophobic, and strength characteristics compared to chitosan films. The possibility of biodegradation of the obtained materials, as well as the dependence of the mass loss of the samples on the HLB level, which can be used to create wound dressings with programmed degradation, is shown.
