Synthesis and Physicochemical Properties of Grafted Copolymers of Chitosan and Acrylic Monomers


The search and analysis of English-language 2004–2019 scientific literature devoted to the graft polymerization of acrylic monomers (acrylic acid and acrylamide being examples) onto chitosan to obtain novel materials with valuable properties was made. It was revealed that radical copolymerization, with potassium or ammonium persulfate, cerium-ammonium nitrate being initiators was used for grafting. Microwave, UV radiation and gamma rays were also used. To obtain gel, a cross-linking agent (N,N’- methylenebisacrylamide) was introduced. Glutaraldehyde was also used for cross-linking. Along with acrylic acid and acrylamide, other monomers (such as hydroxyethyl methacrylate) were also used. In some cases, chitosan was quaternized (using 2,3-epoxypropyltrimethylammonium chloride) or modified (using maleic anhydride, 2-pyridyl-acetylchitosan chloride), some additives were introduced for functionalization (sodium humate, muscovite, attapulgite, silver nanoparticles, and epidermal growth factor). Hydrogels with a double network, nanocomposites based on grafted chitosan, hydrogel microspheres with tunable macroporous structures were of interest in the study. The prospects of using grafted copolymerization products as (super)absorbents (including heavy metal ions), water absorbers, flocculants, antibacterial agents (including nanocomposites), and materials for biomedical engineering (macroporous scaffolds to model nerve tissue) were assessed.
