摘　　要：以乙烯-辛烯接枝马来酸酐（POE—g—MAH）作为相容剂，采用熔融挤出法制备高密度聚乙烯（HDPE）／尼龙6（PA6）共混物。考查了POE—g—MAH用量对共混物形态结构、力学性能、维卡软化点、流变性能的影响。结果表明，POE—g—MAH可提高HDPE／PA6共混物的界面相容性，随着POE—g—MAH用量的增加，共混物的拉伸强度先增加后降低，冲击强度增加，维卡软化点先增加后降低。With ethylene-octane copolymer graft maleic anhydride （POE-g-MAH） as compatibilizer, high density polyethylene/polyamide 6 （HDPE/PA6） was prepared by means of melting extrusion. The effects of the content of POE-g-MAH on morphological structure, mechanical properties, Vicat softening point and rheological property of the blends were studied. The results showed that the addition of POE-g-MAH en- hanced the interracial interaction of HDPE/PA6. With the content of POE-g-MAH increased, the impact strength enhanced the tensile strength and Vicat softening point increased at first and then decreased.
