In this paper, scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and wide‐angle X‐ray diffraction (WAXD) were used to study the structure and compatibilization of poly(propylene) (PP)/nylon‐12 (PA 12) blends. The compatibilization of maleated PP(PP‐MA) and graft copolymer (PP‐MA‐ g ‐PEO) of PP‐MA and poly(ethylene oxide) (PEO) in PP/PA 12 blends was observed from the morphology of the fracture surface of PP/PA12 blends. The compatibilization mechanism was investigated. The DSC results showed that there was nucleation between PP and PA12. This was attributed to the unusual epitaxial relationship. The effect of PA12 on the crystalline structure of PP was studied by means of WAXD.
