Synthesis of graft copolymer (CmgOH-g-NVP) and study of physicochemical properties: Characterization and application

Synthesis and characterization of a novel polymeric hydrogel based on hydroxypropyl methyl cellulose grafted with polyacrylamide

“…Modification of natural polymers by graft copolymerization is anticipated to be quite promising technique as it functionalizes these natural polymers to their potential, imparting desirable properties onto them. Thus, in recent years, an efficient approach to modify the natural polymers in order to synthesize superabsorbent hydrogels, is graft copolymerization of vinylic monomers onto polysaccharide backbones in presence of free radical initiator/crosslinkers (Behari et al 2001;Ghosh et al 2010;Mishra et al 2011;Nayak and Singh 2001;Pandey et al 2006;Singh et al 2006;Tiwari and Singh 2008;Tripathy and Singh 2001). The chemical combination of natural and synthetic polymer yields new materials, which would have desirable properties including biodegradability.…”

Features of the intramolecular structure of branched polymer systems in solution

“…previously introduced into the main chain and oxidizing the main chain with the formation of radicals [95,[98][99][100][101][102][103][104].…”

Synthesis and properties of a water soluble graft (chitosan-g-2-acrylamidoglycolic acid) copolymer

“…grafting of vinyl monomer by using redox initiator system has been developed not only to improve the drawback but also increase the properties of natural polysaccharides. Therefore, several attempts have been made earlier in our laboratory to synthesize the different types of graft copolymer hybrid materials by grafting of different vinyl monomers on to natural polysaccharides [12][13][14][15]. For a new type of graft copolymer hybrid material by using their precursors as chitosan in combination with 2-acrylamidoglycolic acid, in the same way, an attempt has been made to synthesize their corresponding the graft copolymer (chitosan-g-2-acrylamidoglycolic acid).…”
