摘要
综述了近年来聚烯烃茂金属催化剂载体的研究进展,包括新型载体的研制、结构特点及以此载体负载茂金属对聚合产物性能的影响。人工合成的具有空心结构SiO2团粒载体,可望作为一种新型催化剂载体,不仅可以应用于传统催化剂的Ziegler-Natta催化剂、茂金属催化剂,还可以应用于后茂金属催化剂以及非茂金属催化剂等聚烯烃催化剂,替代国外进口载体,实现硅胶作为聚烯烃催化剂载体的国产化。
Research progress in recent years of the polyolefin metallocene catalyst support, which includes the preparation of the novel support, the structure characteristics and performance of the supported metallocene catalyst, on the properties polymerization products, was reviewed. The hollow silica agglomerated support was prepared and likely to be used as a novel catalyst support. The support could be not only applied to classical Ziegler-Natta catalyst and metallocene catalyst as catalyst support, but also applied to post-metallocene catalyst, non-metallocene catalyst and so on as catalyst support for olefin polymerization. The novel support can replace imported support in olefin polymerization and make possible self-made silica gel as catalyst support for olefin polymerization.
