摘　　要：为改善PA6/ABS共混材料的微观结构与相容性,提高该共混材料的性能,分析了聚酰胺6(polyamide 6, PA6)结晶行为、丙烯腈-丁二烯-苯乙烯共聚物(acrylonitrile-butadiene-styrene copolymer, ABS)“核-壳”结构、共混物组成和工艺等条件对PA6/ABS共混材料微观结构与相容性的影响,介绍环氧型和酸酐型反应性增容剂对PA6/ABS共混材料微观结构与性能的影响及其作用机理,并对PA6/ABS共混材料的理论研究和工程应用进行评述.分析表明,随着PA6/ABS共混材料中组分ABS含量增多,PA6的微观形貌由球晶向片晶转变,且ABS“核-壳”结构颗粒可有效增韧PA6;反应性增容剂与PA6/ABS共混材料发生的接枝反应可降低界面张力,使分散相颗粒分布均匀。Aiming at improving microstructure and compatibility of polyamide 6/acrylonitrile-butadiene-styrene copolymer (PA6/ABS) blend materials, and enhancing their properties, this paper investigates some influence factors on the microstructure and compatibility of the PA6/ABS blend materials, including crystallization behavior of PA6, ABS “core-shell” structure, blend composition and process. Especially, this paper reports the effect and mechanism of epoxy and anhydride types of reactive compatibilizers on the microstructure and properties of PA6/ABS blend materials. Additionally, this paper summarizes theoretical research and engineering application of PA6/ABS blends. The results show that with the increase of ABS content in PA6/ABS blend materials, the morphology of PA6 changes from spherical crystal to sheet crystal, and ABS particles with “core-shell” structure can effectively toughen PA6, The grafting chemical reaction, which occurs between reactive compatibilizers and PA6/ABS blend materials, reduces the interfacial tension and makes uniform distribution of dispersed phase particles.
