Abstract: 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.
