摘　　要：系统论述了国内外有关PP增韧改性的研究进展。分别介绍了弹性体或橡胶、热塑性塑料、刚性粒子、刚性粒子协同弹性体、纤维对PP增韧改性的研究现状以及对聚丙烯力学性能、热性能、流变性能的影响,重点介绍了刚性粒子以及刚性粒子协同弹性体对PP的改性研究。刚性粒子协同弹性体能够避免弹性体增韧PP加工上的困难和刚性体在基体中易形成缺陷等问题,充分发挥两者的优势,在对PP增韧改性研究方面具有很大潜力。The newest study progress of toughening PP is summarized. The newest study of toughening PP by using rubber or elastomer blend, thermoplastic plastics, rigid particle, rigid particle coordination with elastomer, fiber and the influence on the mechanical properties,thermal properties and rheology are discussed respectively. The toughening PP with rigid particle and rigid particle coordination with elastomer are expounded emphatically. Synergistic toughening of PP with rigid particle/elastomer can avoid the questions introduced by rigrid partical and elastomer respectively,and so it has great potential on modification of PP in the future.
