摘　　要：聚乙烯(PE)和聚丙烯(PP)是目前生产量和消费量较大的两种塑料,且废弃物总量较多。针对废旧PE/PP的合理利用,探究不同的处理方式。由于简单共混容易导致共混物的力学性能下降,因此,对改善废旧PE/PP的相容性进行探究,分析废旧PE/PP共混物再利用的影响因素,概述常用的增容方法,同时介绍共混物增容策略的研究进展,对增容体系的发展方向进行展望,并重点对纳米增容的前景进行探讨。Polyethyene(PE)and polypropylene(PP)are two kinds of plastics with large production and consumption,and the total amount of waste is more.In view of the reasonable utilization of waste PE/PP,different treatment methods were explored.Simple blending can easily lead to the decrease of mechanical properties of the blends.In order to explore the improvement of the compatibility of waste PE/PP,the influencing factors of the reuse of waste PE/PP blends were analyzed,and the commonly used compatibilization methods were summarized.At the same time,the research progress of compatibilization strategies of blends was introduced.The development direction of compatibilization system was prospected,and the prospect of nano compatibilization was mainly discussed.
