【Abstract】 The effects of polyolefins grafted maleic anhydride as the compatibilizers on the mechanical properties of PO/PA 6 blends were discussed. It is shown that the compatibilizers have good compatibility on PO/PA 6 blends and make the water absorption decreased and that the compatibilizer can result in the fine dispersed phase, increase the interfacial bending as well as the viscosity, and enhance the impact strength of PA 6 matrix, so that the processability of PA 6 is improved.更多还原
