The properties of polyamide 6 (PA6)/poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) blends compatibilized by poly(styrene-co-maleic anhydride) (SMA) were studied. The addition of SMA can form an in situ copolymer, SMA-graft-PA6. The SMA-graft-PA6 copolymer actually plays a key role as a compatibilizer to improve the interface between PA6 and PPO. It was found that the effect of compatibilization resulted in the improvement of the morphology, impact strength, water absorbability and thermal stability of PA6/PPO blends. However, at high SMA contents, the properties of PA6/PPO blends deteriorated to some degree.
