Abstract: Polycarbonate(PC) is thermodynamic incompatible with Nylon 6 (PA6). Addition of compatibilier and modifier in PCand PA6 blends can lower the interface energy, increase the compatibility, and get a stable PC/PA6 alloy. PC/PA6 alloys were prepared by twin screw extrusion compounding process. The mechanical property was measured. The crystal structure and properties were studied with X-ray diffraction(XRD) and differential scanning calorimetry(DSC). The crystal structure of PA6 is affected dramatically and a new crystal form is formed because the introduction of compatibilier and modifier enhanced the interaction between PCand PA6. The crystallinity is decreased and the crystallization kinetics is slowed down. The high performance PC/PA6 alloy has been obtained.
