摘　　要：以提高聚丙烯的抗冲性能为背景,综述了得到普遍认可的银纹-剪切带理论和空穴理论增韧机理,物理改性(共聚共混改性、添加成核剂改性、填充改性)和化学改性(接枝改性、交联改性、化学共聚改性)增韧方法,指出了各改性方法的优缺点,并对抗冲聚丙烯未来发展前景进行了展望。In order to improve the impact resistance of polypropylene,the toughening mechanisms of silver grain-shear band theory and cavity theory,as well as toughening methods of physical modification(copolymer blending modification,nucleating agent addition modification,filling modification)and chemical modification(graft modification,cross-linking modification,chemical copolymer modification)are reviewed.In addition,the advantages and disadvantages of each method are pointed out,and the future development of impact resistant polypropylene is prospected.
