摘　　要：Non-metallocene catalysts have emerged as a promising alternative to traditional metallocene catalysts for olefin polymerization,offering unique advantages regarding polymer structure control and product diversity.Recent advancements in ligand design and synthesis have led to the development of highly active and selective non-metallocene catalysts capable of producing polyolefins with tailored properties.These catalysts exhibit enhanced thermal stability,improved comonomer incorporation,and the ability to polymerize a wider range of monomers.Furthermore,nonmetallocene catalysts have shown potential as promising compounds for the production of novel polymer architectures,including hyperbranched and stereoblock polymers.This work provides an overview of the current state of non-metallocene catalysts for olefin polymerization,examining their advantages,challenges,and future prospects in the field of polymer synthesis.
