Progress on metallocene catalysts for olefin polymerization
Due to its excellent performance,polyolefin products are widely used in various fields and are closely related to human daily production and life.Metallocene catalysts have played an important role in the polyolefin industry due to their advantages of effectively regulating the microstructure of polymers,having a single active center,and high catalytic efficiency.This article reviews the research progress in metallocene catalysts from the aspects of their types,structures,and types of co-catalysts,and looks forward to their research directions.
