Syntheses and characterisation of graft copolymers of maize starch and methacrylonitrile

Curdlan-Conjugated PLGA Nanoparticles Possess Macrophage Stimulant Activity and Drug Delivery Capabilities

“…Previous studies have shown that the grafting of molecules onto a polymer chain can reduce thermal stability due to the incorporation of some "weak links" into the polymer structure [21,22]. A further indication of conjugation can be obtained from changes in the char residue, as previous studies have shown that greater residues are associated with increased grafting yields [22,23]. PLGA-COOH and curdlan show char residues of 0.3 and 5wt%, respectively, while C-PLGA shows a residue of 10 wt%.…”

A review of the recent developments in biocomposites based on natural fibres and their application perspectives

“…By reaction of its hydroxyl (OH) group, modification of various properties can be obtained, leading to materials with different properties [36]. Different strategies have been widely studied in order to improve starch mechanical and barrier performance and reduce its hydrophilic nature, like adding crosslinking agents, such as graft copolymerization [41], blending with thermoplastic polymers [42], chemical modification [43], and development of multilayer structures [44]. Among these techniques, many authors have proposed blending of starch physically with other degradable polymers, to enhance microstructures, such as co-continuous structure can be formed by melt blending.…”

Ceric ammonium nitrate‐initiated graft copolymerization of acrylamide onto Cassia tora gum

“…Among chemical methods, redox-initiated grafting offers advantages because, in the presence of redox systems, grafting can be carried out under milder conditions with minimum side reactions. Grafting of vinyl monomers onto natural polymers like guar gum, 1,2 starch, 3,4 and cereal flour 5 with different redox initiators has been studied. Cassia tora gum (CTG) is derived from the seeds of Cassia toraLinn, a common herbaceous annual occurring weed throughout India.…”
