Grafting of maleic anhydride onto polypropylene in xylene medium initiated by benzoyl peroxide under nitrogen atmosphere has been studied. The effects of reaction time. Reaction temperature, maleic anhydride concentration, benzoyl peroxide and material to monomer ratio have been studied in terms of 34 GE and % Add-on, The optimum conditions obtained for the grafting of maleic anhydride on 5.0 g of polypropylene were [BPO] 8.25 x 10 mol/L, (MAHI 2.04 x 10 mol/L. temperature 120 °C, time = 300 mm and polypropylene to solvent ratio 1:2 0. The graft copolymèr was characterized by FTIR spectrum.
