In this research, we synthesize of a graft copolymer based on alginate via simultaneously graft copolymerization acrylamide (AAm) and  2-acrylamido-2-methylpropanesulfonic acid (AMPS) onto alginate backbones. The polymerization reaction was carried out in an aqueous medium and in the presence of ammonium persulfate (APS) as an initiator. Infrared spectroscopy and TGA thermal analysis were carried out to confirm the chemical structure of the copolymer. A proposed mechanism for hydrogel formation was suggested.
