As an important component of Ziegler-Natta catalysts
support materials show profound influences on catalyst properties as well as polyolefin particle morphology and structure and properties. Advancement in support technology is thus contributing greatly to the innovations of Ziegler-Natta catalysts and the development of high-performance polyolefin materials. This paper reviewed the recent research progress in Ziegler-Natta catalyst support technology
including those on magnesium-alcohol support
inorganic salt-doped MgCl

support
hybrid MgCl
