The products obtained as a result of the simultaneous reaction of chitosan, a Schiff-based natural polyaminosaccharide, with formaldehyde and benzaldehyde were synthesized by the method indicated in the experimental part of the article. The two amine groups formed were then reduced with NaBH4 to give the corresponding tertiary amine derivative. The structure of the obtained product was characterized by scanning electron microscopy and elemental analysis was determined. The introduction of hydrophobic methyl and benzyl groups into the macromolecule of chitosan reduces the intermolecular interaction and hydrogen bonding. causes. This leads to an increase in the degree of polarization and better solubility of the functional groups of the product in the polar environment.
