摘　　要：聚丙烯具有密度低、耐化学性好、耐磨性优良和电绝缘性突出等众多优点,被广泛的应用于机械、汽车、电子电器、建筑、纺织、包装等领域。但是,聚丙烯也存在力学性能不足和耐热性差的问题,严重限制了其在工程领域的应用。为了解决这些问题,可以通过对聚丙烯进行化学改性和物理改性以改善它的性能不足,赋予其更多的新的性能,拓宽其应用范围。本论文主要介绍了目前聚丙烯的常用改性方法和改性机理,总结了聚丙烯改性各种方法的特点、应用及展望。Polypropylene has a variety of advantages, such as low density, good chemical resistance, excellent abrasion resistance and outstanding electrical insulation. It is widely applied in machinery, auto-mobile, electronic appliances, construction, textile, packaging and other fields. However, polypro-pylene has several disadvantages including insufficient mechanical properties and poor heat re-sistance, which severely limits its application in the engineering field. In order to solve these prob-lems, we can improve the performance of polypropylene by chemical and physical modification, endowing polypropylene with more new properties and broadening its application range. This pa-per mainly introduces the commonly used modification methods and mechanisms of polypropyl-ene, and summarizes the characteristics, applications and prospects of various methods that used in polypropylene modification.
