In this article; maleated-grafted ethylene-co-vinyl acetate (EVA-g-MA) was used as the interfacial modifier for polypropylene/polyamide-6 (PP/PA6) blends; and effects of its concentration on the mechanical properties and the morphology of blends were investigated. It was found that the addition of EVA-g-MA improved the compatibility between PP and PA6 and resulted in a finer dispersion of dispersed PA6 phase. In comparison with uncompatibilized PP/PA6 blend; a significant reduction in the size of dispersed PA6 domain was observed. Toluene-etched micro graphs confirmed the formation of interfacial copolymers. Mechanical measurement revealed that the addition of EVA-g-MA markedly improved the impact toughness of PP/PA6 blend. Fractograph micrographs revealed that matrix shear yielding began to occur when EVA-g-MA concentration was increased upto 18 wt %. © 2006 Wiley Periodicals; Inc;
