Аннотация
Graft copolymers of chitosan with acrylic acid of three-dimensional structure have been synthesized. An increase in the concentration of the polysaccharide helps to accelerate the structure formation of copolymer macromolecules during the synthesis. It has been shown that one of the reasons for this effect is a local increase in the concentration of acrylic acid in the chain growth zone due to the formation of hydrogen bonds between the monomer and the polysaccharide. The graft copolymers have been characterized by IR and UV spectroscopy, AFM, and X-ray diffraction and can be used as highly swelling superabsorbents.
