Ternary polymer blends based on polyamide 6 (PA6)/polycarbonate (PC)/acrylonitrile-butadiene rubber (NBR) were prepared at fixed compositions using a twin-screw extruder. The ternary blends mixed at 240 ̊C of die temperature and 130 rpm of screw speed at different levels of blending sequence (B.S1-B.S2-B.S3). In B.S1, the blending sequence, all components were extruded simultaneously but in B.S2 and B.S3 blending sequences, the produced master batch of PC+NBR and PA6+PC were added to the other absent phase. The mechanical properties of ternary blends were influenced by mixing method and the results of mechanical testing were confirmed using the field emission scanning electron microscopy (FESEM) micrographs.
