摘　　要：从晶体形貌、晶体结构、外力的耗散方式及非晶区结构这四个方面归纳近年来新型的聚丙烯增韧改性的研究进展,并结合经典的增韧机理,对不同增韧方式的内在机理进行了深入的探讨与分析。提出了聚丙烯增韧的核心要点在于提高外力在基体内的耗散效果,并基于此展望了未来的研究方向。The novel and effective toughening modifications of polypropylene in recent years are systematically reviewed. Different toughening systems have been summarized from four aspects such as the crystal morphology, the crystal structure, the way of external force dissipation and the amorphous structure. Based on the classical toughening mechanisms, the internal mechanisms of these four toughening methods have been deeply investigated and analyzed. It is emphasized that the enhancement of the dissipation of external force in the matrix is the key point of toughening polypropylene, on which further research prospects are also proposed.
