Изучено влияние диаметра трубчатого реактора и направления движения фронта на протекание процесса фронтальной сополимеризации акриламида и акрилата натрия в водных растворах. Показано, что скорость фронта практически не зависит от диаметра трубчатого реактора, а температура фронта снижается с увеличением диаметра. Определены величины водопоглощения и гель-фракции полученных гидрогелей.</p></abstract><trans-abstract xml:lang="en"><p>The objects of study were the process of frontal copolymerization of acrylamide with sodium acrylate in aqueous solutions in tubular reactors of various diameters and with different directions of front propagation, as well as the resulting copolymers and hydrogels. The effect of the diameter of a tubular reactor and the direction of front propagation on the process of frontal copolymerization of acrylamide and sodium acrylate in aqueous solutions has been studied. It was shown that the front velocity is almost independent of the diameter of the tubular reactor, and the front temperature decreases with increasing diameter. The values of water absorption and gel-fraction of the obtained hydrogels were determined.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фронтальная сополимеризация</kwd><kwd>акриламид</kwd><kwd>2-акриламидо-2-метилпропансульфокислота</kwd><kwd>полиэлектролитный гидрогель</kwd><kwd>направление движения фронта полимеризации</kwd><kwd>водопоглощение</kwd><kwd>гель-фракция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>frontal polymerization</kwd><kwd>acrylamide</kwd><kwd>sodium acrylate</kwd><kwd>acrylic acid</kwd><kwd>polyelectrolyte hydrogel</kwd><kwd>water absorption</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Deep Eutectic Solvents as Both Active Fillers and Monomers for Frontal Polymerization / J.
