摘要：
The properties of polyamide 6 (PA6)/poly(2,6dimethyl- 1,4-phenylene oxide) (PPO) blends (60/40, wt%) 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 improvement of the morphology, impact strength and water absorbability of PA6/PPO blends (60/40, wt%), but with no favorable effects for thermal stability. However, at high SMA contents, the properties of PA6/PPO (60/ 40, wt%) blends deteriorated to some degree.
