Description

technical field

[0001] The present invention relates to a ligand compound for olefin polymerization catalysts, transition metal complexes synthesized from the ligand compounds and olefin polymerization catalysts containing transition metal complexes. The invention also relates to the olefin polymerization catalysts used in olefin polymerization in the application. technical background

[0002] With the continuous development of the polyolefin industry, many types of polyolefin catalysts have emerged, mainly including Ziegler-Natta catalysts, metallocene catalysts, and non-molecene single-site catalysts. Since the invention of the Ziegler-Natta catalytic system, a large number of improved catalysts have appeared, but due to their low catalytic activity and unsatisfactory copolymerization performance, they have been replaced by recently discovered metallocene catalysts in recent years. Typical metallocene catalysts consist of transition metal compounds with one or more cyclop...
