ResumoAbstract The synthesis of sodium alginate‐ g ‐polyacrylamide was carried out by a ceric‐ion‐induced solution polymerization technique. Six grades of graft copolymers were synthesized by the variation of catalyst and monomer concentrations. These graft copolymers were characterized by intrinsic viscosity measurements, 13 C‐NMR spectroscopy, infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, and X‐ray diffraction. From the characterizations, it could be concluded that there was a substantial amount of grafting with a minimum formation of homopolymer. © 2001 John Wiley & Sons, Inc.
