The morphology of polyamide 1010/polypropylene blends was found to significantly depend upon the concentration of the compatibilizer[polypropylene‐grafted‐acrylic acid (PP‐g‐AA)]. A significant reduction in phase size was observed because of the interaction that existed between the PP‐g‐AA and polyamide. These interactions have been confirmed by several methods. The tensile mechanical properties and impact behavior of the prepared blends were investigated and correlated with scanning electron microscope (SEM) analysis of the fracture surfaces. It was found that PP‐g‐AA as the compatibilizer has a profound effect upon the properties of the blends. This behavior is attributed to a series of chemical and physico‐chemical interactions taking place between the two components.
