“…Atom transfer radical polymerization (ATRP) which is one of modification methods has been extensively studied for graft copolymerization of vinyl monomers onto cellulose and cellulose derivative [3]. This method can produce copolymer with controlled graft density and length as well as low polydispersity index [4]. In addition, the formation of homopolymer is neckligible [5].…”

Abstract. The synthesis of a cationic cellulose copolymer from cellulose macro-initiator (MCC-BiB) and quaternary compound monomer (METMA) via atom transfer radical polymerization (ATRP) was studied. By using dimethylformamide (DMF), the optimum condition for successful synthesis was at the mole ratio of MCC-BIB: Catalyst:METMA = 1:1:26. The highest copolymer recovery was 93.2 % for 6 h and at 40 o C. The copolymer was insoluble in weak polar solvents such as THF and DMF but soluble in methanol and water. The chemistry of cellulose copolymer was confirmed by the FTIR and TGA in which the METMA monomer was used as a reference. The absence of C=C bond in the CiB-g-METMA spectrum indicated that graft copolymerization occurred.

“…Another widespread approach to obviate these solubility issues consists in partially converting the abundant hydroxyl functions located on the polysaccharide precursors into alkoxyl or acetate groups. Acetylated dextran30 and starch31 backbones have been described as starting materials for the generation of polysaccharide‐ g ‐PMMA copolymers. Cellulose ether and ester derivatives, i.e., HPC, cellulose diacetate (CDA), methyl or ethyl cellulose (MC, EC) have also been extensively investigated as precursors for the preparation of a large range of hybrid graft copolymers by ATRP 32–40.…”

“…Graft polymerization is a well-known method for the modification of chemical and physical structure to tailor properties for specific application. This method is of particular interest to achieve specifically designed polymer properties by connecting different types of polymers having the desired properties in the same polymer chain (Nurmi et al 2007). The advantages in the use of the grafting reaction consist in the functionalization of the materials without affecting its bulk properties, elimination of the need to redesign the bulk material to achieve a target surface performance and a considerably reduction of the cost.…”

As consumers are demanding polymeric materials more natural, disposable, biodegradable and recyclable, the interest in active food-packaging systems in which the polymer matrix has low environmental impact is growing significantly. To this regard, the insertion of antioxidant molecules onto polysaccharides backbone is an innovative strategy to produce biocompatible species suitable for foodpackaging applications. Moreover, free radical grafting is a method which allows the synthesis of antioxidant biomacromolecule without the use of organic solvents or toxic radical initiators. In the present study, quercetin, catechin and gallic acid were bound to chitosan, starch, inulin and alginate using this technique and good antioxidant activity of the conjugates were observed. This can be useful in the optimization of food preservation and to help manufacturers in elaboration of new and sustainable food products and packaging.
