摘　　要：官能化聚烯烃是由聚烯烃改性后得到的产物,一般通过交联改性、共聚改性、固相力化学改性和接枝改性等方法制备,可应用于黏附、能源和封装等多重领域。基于聚烯烃高通量低成本的优势,聚烯烃接枝改性利用自由基反应直接向聚烯烃链上引入极性单体,较为经济便捷。聚烯烃接枝改性按反应条件的不同,又可分为溶液接枝、熔融接枝、辐射接枝、固相接枝和悬浮接枝。在接枝改性过程中,接枝率和接枝效率受多种因素影响,如聚烯烃型号、接枝单体、引发剂、共单体和反应条件等。本文综述了聚烯烃接枝改性不同接枝方法的研究进展,分析了各种接枝方法的优势和短板,并将接枝改性过程中的影响因素进行了总结。文章依据聚烯烃的可控自由基接枝改性和金属催化改性以及官能化聚烯烃的应用,展望了聚烯烃可控改性和官能化聚烯烃规模化生产。Functionalized polyolefin is a modified product of polyolefin that can be applied to multiple fields,such as adhesion,energy and packaging.It is generally prepared by grafting,cross-linking,copolymerization,etc.Based on the large scale and low price of polyolefin,polyolefin grafting modification directly introduces the wide range of functional groups onto a polyolefin backbone by radical-induced grafting,which is the most economical and convenient.Due to the differences of reaction condition,polyolefin graft modification can be divided into solution grafting,melt grafting,irradiation grafting,solid phase grafting and suspension grafting.In the process of graft modification,the grafting degree and grafting efficiency are affected by many factors,such as polyolefin type,grafting monomer,initiator,comonomers and reaction conditions.This paper reviews the research progress of the grafting methods,the advantages and shortcomings of different grafting methods and analyzes the influence factors in the process of graft modification.According to the controllable free radical grafting modification and metal catalyzes modification of polyolefins,as well as the application of functionalized polyolefins,the controllable modification of functionalized polyolefins and large-scale production are prospected.
