To graft acylamide (AM) onto the backbone of natural water-soluble polysaccharide of P.psyllium mucilage (PSY), ceric ion initiated solution polymerization technique was reported for the first time. This technique was found to be beneficial. The effects of varying concentration of AM and ceric ammonium nitrate (CAN) on graft copolymerization have been studied. The prepared copolymers were characterized by FTIR. The % grafting and the intrinsic viscosity of this water-soluble copolymer were found to be affected by the concentration of AM and CAN in the reaction mixture.
