摘　　要：结合近年来的研究成果,对无规共聚改性、嵌段共聚改性、接枝共聚改性、改变立体结构、橡-塑共混改性、塑-塑共混改性、纤维填料改性、无机粒子改性、β晶型成核剂改性、纳米复合改性、多组分复合改性等多种聚丙烯的增韧方法及其机理进行了综述;指出橡-塑共混改性依然是目前最有效的增韧方法,多组分复合增韧是今后的发展方向。Based on recent research advance, toughening methods and mechanisms of PP, including ruleless copolymerization, block copolymerization, graft copolymerization, altering stereo-structure, rubber-plastic blending, plastic-plastic blending, fibre filling modification, inorganic particle modification, β crystalline form nucleating agent modification, nano-composite modification and multi-composite modification, were reviewed. It was concluded that at present rubber-plastic blending toughening was best toughening method, and in the future multi-composite toughening modification was the development direction.
