摘　　要：催化剂及催化技术的发展是聚烯烃产业技术进步的核心。硅胶作为聚烯烃催化剂常用的载体材料,在催化剂的合成及聚烯烃树脂的制备领域发挥着重要的作用。近年来,关于硅胶负载聚烯烃催化剂的研究已陆续发表。本文综述了硅胶载体的结构、制备方法以及硅胶载体与聚烯烃催化剂(Ziegler-Natta催化剂、茂金属催化剂、后过渡金属催化剂及铬基催化剂)负载化的研究进展,并介绍了催化剂的制备机理、优点及应用。The evolution of catalyst and catalyst technologies is essential to the technological progress of the polyolefin industry.Silica gel,a common carrier material,plays an important role in catalyst synthesis and the industrial production of polyolefin plastics.Recently,several studies on the status and trend of silica gel-supported polyolefin catalystshave been published.This paper presents the silica gel support structure,preparation methods,and the research progress of silica gel-supported polyolefin catalysts(such as Ziegler-Natta,metallocene,post-transition metal,and chromium-based catalysts).Furthermore,the preparation mechanism,advantages and applications of catalysts are introduced.
