Preparation of Chlorinated maleic anhydride grafted polypropylene (Cl‐PP‐ g ‐MAH) by free radical process was carried out using carbon tetrachloride (CCl 4 ) as the solvent and benzoperoxide (BPO) as the initiator. Effects of reaction temperature, concentrations of PP‐ g ‐MAH and BPO on the rate of chlorination were studied. The experimental results showed the actual rate constant for chlorination of maleic anhydride grafted polypropylene followed the Arrhenius law and the total apparent activation energy was 19.7 kJ mol −1 . The kinetic model for chlorination of maleic anhydride grafted polypropylene was found to be R = K [BPO] 0.53 [C] 0.93 . The properties of chlorination of maleic anhydride grafted polypropylene were better than those of maleic anhydride grafted polypropylene. The products were characterized by Fourier transform infrared spectroscopy. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
