Free-radical dual grafting of maleic anhydride(MAH) and styrene(St) onto granular polypropylene(PP) using supercritical CO2 as a solvent and swelling agent has been studied and PP-g-(MAH-St) prepared. The effect of molar ratio of monomers, swelling temperature and time, reaction time and pressure on the grafting density are discussed. It is found that the St as a co-monomer in the grafting reaction system could significantly enhance the grafting density of PP for MAH and St on PP. The maximum grafting density for PP-g-(MAH-St) in supercritical CO2 fluid under optimal reaction conditions was 10.58%, two times that for PP-g-MAH. The process is simpler than regular graft polymerization processes. The structures and properties of the graft copolymers were characterized by FTIR and DSC. The results indicate that styrene branch chains reduces the Tm of PP from 158℃ to 154℃.
