Description

technical field [0001] The invention relates to a class of arylamino ether metal complexes, a preparation method thereof, a catalyst composition containing the complexes, and its application in catalyzing olefin polymerization, especially ethylene homopolymerization or ethylene and alpha-olefin copolymerization. Background technique [0002] Metallocene catalysts have shown high catalytic activity and controllability to the microstructure of polymerization products in catalyzing olefin polymerization, and have successfully prepared a variety of olefin polymers. The unique cyclopentadiene group of metallocene catalysts can control the stereotype and electronegativity of the active center during the catalytic process to form a single active center. Metallocene catalysts with constrained geometry not only have high activity characteristics, but also exhibit excellent thermal stability and copolymerization performance, and have industrial application value for the production of ...
