镍配合物催化的α-烯烃聚合研究进展OA

The market demand for high-end polyolefins and high-end synthetic lubricants has increased continuously,drawing significant attention to the polymerization of long-chain α-olefin.The catalysts serve as one of the key factors in the polymerization process.With unique chain walking capability,late-transition metal catalysts show great potential for developing brand-new polyolefin materials.Among those catalysts,nickel complex catalysts are much more widely used thanks to the cost-effectiveness.With a focus on the application of nickel complex catalysts in α-olefin polymerization,recent research advances in this field are reviewed,including the catalytic activity of nickel complex catalysts with various structures,the polymer microstructures,and the correlation between the polymer microstructures and macroscopic properties.Perspectives on the future development of this field are also provided.
