Starch has been chemically modified by graft copolymerization of 2-hydroxyethylacrylate (HEMA) and acrylic acid(AcA) an aqueous medium using ammonium persulfate (APS) as an initiator under argon atmosphere. A plausible reaction mechanism of grafting has been suggested. Evidence of grafting was obtained by comparison of FTIR spectra of starch and homopolymer-free St-g-poly(HEMA-co-AcA) as well as solubility characteristics and gravimetric analysis of the products. The optimum reaction conditions affording maximum grafting ratio and add-on value have been determined. The grafting parameters have been found to increase with increasing in starch, APS,AcA and HEMA concentrations up to a certain value, but these parameters decrease on further increasing in reaction conditions.
