โœฆ Synopsis


Graft copolymers of polyacrylamide with starch, amylose, and amylopectin have been synthesized using ceric-ion-induced redox initiation technique. The polymers were characterized using different instrumental techniques like thermal, XRD, SEM, IR, NMR, and elemental analysis. The results indicated that there is a substantial amount of grafting with minimum formation of homopolyacrylamide.

Graft copolymers of starch, amylose, and amylopectin with polyacrylamide have been synthesized using a ceric-ion-initiated solution polymerization technique. In the case of amylopectin-g-polyacrylamide ( Ap-g-PAM ) , four graft copolymers have been synthesized with variation in the number and length

Various polysaccharides, such as starch and its constituent amylopectin, are used as flocculants in industrial effluent treatment. Grafting them with polyacrylamide branches enhances their flocculating and turbulent drag-reducing characteristics drastically. Aqueous solutions of the graft copolymer
