摘　　要：丙烯腈/苯乙烯/丙烯酸酯接枝共聚物(ASA)是由以聚丙烯酸酯(PBA)橡胶相为核,苯乙烯-丙烯腈共聚物(SAN)为壳的核壳结构聚合物。具有良好的机械性能、耐腐蚀性、加工性、抗冲击性能和耐候性。本文综述了ASA接枝共聚物的合成,ASA树脂的制备及改性,以及ASA树脂与PVC、PC、PBT、PMMA、PA等材料共混合金的研究进展,发现国内外对ASA合金的基础研究较少。开发耐候性好,具有高性能、功能化的ASA基材料将是ASA研究的新的方向。Acrylonitrile/styrene/acrylate graft copolymer （ ASA） is a core-shell structure polymer, which is the core of the PBA rubber. ASA has good mechanical properties, corrosion resistance, impact resistance and weather resistance. The synthesis of ASA graft copolymer, the preparation and modification of ASA resin were discussed, and the research progress of ASA resin with PⅤC, PBT, PC, PMMA, PA or other materials were summarized. The basic research of ASA alloy was little at home and abroad. Development of good weather resistance, high performance, functional ASA based material will be the new direction of ASA research.
