| Abstract: | By acylating chitosan with maleic anhydride in formamide medium trisubstituted products (on one amine and two hydroxyl groups of the saccharide unit) have been obtained, as has been confirmed by IR spectroscopy, titration carboxylic groups, and determination of the content of olefin bonds. By copolymerizing trisubstituted maleilated chitosan and acrylamide in water solution crosslinked polymers have been obtained. Their swelling in water decreases with an increase in the share of maleilated chitosan in the initial mixture of reagents and with a decrease in dilution of the initial mixture of reaction components. Consumption of maleilated chitosan double bonds in this case varies from 40 to 70%. |
