“…The type of polymerization to be selected depends on the type of monomer to be grafted; in most cases, radical polymerization has been used [ 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 ], although there is also a report of anionic ring-opening polymerization [ 90 ]. Acrylic monomers (especially acrylic acid) are among the most frequently grafted into chitin [ 82 , 83 , 84 , 85 , 88 , 91 , 92 , 93 ]. For the development of experimental procedures, it must be taken into account that chitin is not soluble in aqueous media and, therefore, the reaction must be carried out mostly under heterogeneous conditions.…”

“…The grafting from copolymerization of acrylic monomers onto chitin using cerium (IV) as redox initiator has been the subject of some studies [ 82 , 83 , 84 , 93 ]. In the pioneering work by Kurita et al, the influence of several conditions of the copolymerization reaction of acrylamide and acrylic acid onto chitin was investigated [ 82 ].…”

The functionalization of polymeric substances is of great interest for the development of innovative materials for advanced applications. For many decades, the functionalization of chitosan has been a convenient way to improve its properties with the aim of preparing new materials with specialized characteristics. In the present review, we summarize the latest methods for the modification and derivatization of chitin and chitosan under experimental conditions, which allow a control over the macromolecular architecture. This is because an understanding of the interdependence between chemical structure and properties is an important condition for proposing innovative materials. New advances in methods and strategies of functionalization such as the click chemistry approach, grafting onto copolymerization, coupling with cyclodextrins, and reactions in ionic liquids are discussed.

Modification of chitin by grafting with itaconic acid (IA) was carried out using potassium persulfate as redox initiator. In complimentary experiments, grafting was performed using γ‐radiation. Grafting was confirmed by FTIR spectroscopy. The effect of monomer concentration, initiator concentration and copolymerization temperature on the percentage of grafting were studied. The effect of radiation dose was also investigated. Values for percentages of grafting of up to 300 % were reached. It was observed that the percentage of grafting increased with increasing monomer concentration and showed a tendency to level off at IA concentration of 0.1 mol l−1. The percentage of grafting increased with temperature up to 60 °C and then decreased. The solubility of the grafted chitin was studied in organic and inorganic solvents. The complexation of the grafted chitin with some cations, namely copper, nickel, cobalt, zinc and lead, was also investigated. The metal uptake was measured by UV spectroscopy. Thermogravimetric analysis of the grafted chitin was also studied. Copyright © 2004 Society of Chemical Industry
