Структура привитого сополимера хитозана с акриламидом изучена методами Фурье-ИК спектроскопии, рентгенофазового анализа и совмещенного термического анализа. Установлено, что центрами прививки растущих цепей полиакриламида на макромолекулах хитозана являются как гидроксильные, так и аминогруппы полисахарида. Изучено влияние мольных отношений реагентов на сорбционные и реологические свойства полученных гидрогелей. Проведено химическое модифицирование гидрогелей на основе привитых сополимеров хитозана с акриламидом посредством щелочного гидролиза и установлено его влияние на сорбционную способность гидрогелей по отношению к воде и ионам Cu(II).</p></abstract><trans-abstract xml:lang="en"><p>Hybrid hydrogels have been synthesized by radiation grafting of acrylamide to chitosan chains. The structure of the acrylamide-grafted chitosan was examined using FTIR spectroscopy, X-ray diffraction and simultaneous thermal analysis. It has been determined that both hydroxyl and amino groups of the polysaccharide are the grafting centers of growing polyacrylamide chains on the chitosan macromolecules. The effect of the reagents ratio on the sorption and rheological properties of the obtained hydrogels has been studied. Hydrogels based on acrylamide-grafted chitosan were modified chemically by alkaline hydrolysis, and the effect of hydrolysis on the sorption capacity of hydrogels with respect to water and Cu(II) ions was examined.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хитозан</kwd><kwd>акриламид</kwd><kwd>гамма-облучение</kwd><kwd>радиационное инициирование</kwd><kwd>радикальная прививочная сополимеризация</kwd><kwd>гидрогель</kwd><kwd>сорбционная способность</kwd><kwd>ионы Cu(II)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chitosan</kwd><kwd>acrylamide</kwd><kwd>gamma irradiation</kwd><kwd>radiation initiation</kwd><kwd>radical grafting copolymerization</kwd><kwd>hydrogel</kwd><kwd>sorption capacity</kwd><kwd>Cu(II) ions</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Белорусского республиканского фонда фундаментальных исследований (грант № Х22УЗБ-025) «Новые методы получения гибридных полимерных суперабсорбентов на основе полисахаридов и полиакрилатов».</funding-statement><funding-statement xml:lang="en">The research was supported financially by the BRFFR (grant no.
