Catalyst Design Concept for Acquiring High-Activity Catalysts

2 Catalyst Design Concept for Acquiring High-Activity Catalysts 

A transition-metal-based olefin polymerization catalyst is generally comprised of a metal, ligand(s), a growing polymer chain, a coordinated olefin, and a cocatalyst (activator), as depicted in Fig. 5.
