Graft Polymerization: Starch as a Model Substrate

Gum ghatti based novel electrically conductive biomaterials: A study of conductivity and surface morphology

“…Reaction time was found to possess an important role in getting the synthesized samples with higher water absorbency. However, after attaining the optimum reaction time further increment resulted in a decreased percentage swelling (Figure 5b), which again could be due to excessive crosslinking resulting in more compactness and rigidity [37].…”

Water absorption, retention and the swelling characteristics of cassava starch grafted with polyacrylic acid

“…To characterize the extent and efficiency of the grafting reaction, parameters like add-on and grafting efficiency (GE) are commonly used (Athawale & Rathi, 1999;Park, Song, & Song, 1999;Patil & Fanta, 1993;Vera-Pacheco, Vázquez-Torres, & Canché-Escamilla, 1993). Add-on depicts the weight ratio of the grafted polymer to the total grafted product.…”

Graft copolymerization of acrylic acid onto hydrolyzed potato starch using various initiators

“…Increasing the grafting efficiency is an effective way of improving the properties of starch graft copolymers and reducing their preparation costs [18,19]. However, the graft copolymerization of starch with vinyl monomers is always accompanied by the homopolymerization of vinyl monomers as reactants.…”
