Abstract Effects of blend composition, compatibilizer, and processing conditions on the morphology, rheology, and mechanical properties of the ternary blends are investigated. Introduction of compatibilizer and increasing shear rate lead to a finer particle dispersion. A modification of Wu's equation is utilized to obtain an estimate of the interfacial tension. The results indicate a reduction in interfacial tension upon addition of compatibilizer. Morphological stability of these blends is studied by reprocessing them in an injection molding machine and a twin‐screw extruder. The nature of the reprocessing history was found to govern the morphology and the mechanical properties of the blends investigated.
