The graft copolymerization of poly(vinyl acetate) [poly(VAc)] onto starch was studied using the KMnO 4 -H 2 SO 4  redox system. The grafting parameters are favored by changing the concentration of KMnO 4 , the concentration of acid, the temperature, the time, and the concentration of monomer. A maximum graft yield of 38.3% was obtained at optimum conditions: KMnO 4  concentration=3.0×10 -3  mol/l, concentration of acid=1.5×10 -2  mol/l, temperature=40°C, time=3 h, and concentration of monomer=1 mol/l. The grafting of poly(VAc) onto starch was confirmed by the IR spectra of pure sago starch, poly(VAc), and poly(VAc) grafted starch. Both swelling power and solubility increased with the increase in temperature. Graft copolymerization increased swelling power and reduced solubility. This material may have use as an application as a biodegradable plastic.
