Blends of nylon 6 and ethylene–propylene rubber, grafted with maleic anhydride, (EPR-g-MA) were prepared using a melt blending process. For certain compositions, nylon 6 forms finely dispersed particles due to the reaction of the polyamide amine end groups with the grafted maleic anhydride, that have the potential to reinforce the elastomer matrix. This study focuses on the effects of the content of nylon 6 on the rheological, morphological and mechanical properties of such blends where nylon 6 is the dispersed phase. Transmission electron microscopy was used to determine blend morphology. Mechanical properties were examined by stress–strain measurements and dynamic mechanical thermal measurements; the modulus is compared to values calculated from theory. The addition of magnesium oxide causes significant improvement in tensile properties of these blends.
