The research progresses about polyolefin catalyst systems in recent years are summarized. Focusing on the type and properties of the catalytic polymerization of the olefin polymerization catalyst, including typical Ziegler-Natta catalysts, metallocene catalysts and post-transition metal catalyst system. Then the new post-transition metal catalyst is introduced.
