The grafting degree and shear viscosity under constant shear stress of PP-g-MAH as function of contents of MAH, dicumyl peroxide(DCP) and additives has been investigated. The mechanism of melt grafting of polypropylene(PP) with maleic anhydride(MAH) proposed previously by authors is proved to be correct through reactive extrusion. It is evident that decreasing the tendency of reaction between the peroxide radicals and the MAH monomer and enhancing the tendency of reaction between the macromolecular radicals and MAH will result in the formation of final product having higher grafting degree and higher molecular weight simultaneously.
