A new grafting method was developed to incorporate maleic anhydride directly onto solid-state polypropylene powders. Maleic anhydride grafts altered the nonpolar characteristics of polypropylene so that much better mixing was achieved in blends and composites of polypropylene with many other polymers and fillers. Maleic anhydride was grafted onto polypropylene by the peroxide-catalyzed swell grafting method, with a maximum extent of grafting of 4.60%.
