Progress of Olefin Coordination Polymerization in Recent 20 Years

Polyolefin is the synthesized resin that has the maximum consumption. The excellent performance of polyolefin gains its wide applications. Olefin coordination polymerization technologies involving catalysts, polymerization methods and polymerization process were developed greatly in recent 20 years. In this paper, the recent developments in Ziegler-Natta catalysts, metallocene catalysts, non-metallocene catalysts, the mechanism of coordination polymerization, the synthesis of functional polyolefins, the synthesis of LLDPE by in situ copolymerization, the synthesis of nanocomposite by in situ polymerization, living coordination polymerization and Spherizone process were summarized.
