Organometallic Complexes as Catalysts for Olefin Polymerization

Organometallic catalysts play an important role in the polymerization of olefins. These catalysts have high catalytic activity with molecular tailoring properties. They are able to tailor the microstructure of the polymer chain by changing functional groups and coordination atoms of ligands, or by alternating electronic and stereoscopic en-vironments of coordination center in catalysts. Molecular design and assembly of catalysts can be achieved at molecular level. New types of polymers with novel structures, morphology, properties and functions can be ob-tained. Herein, we reviewed the discovery, development, the polymerization characteristics and the most signifi-cant recent studies of organometallic catalysts for olefin polymerization.
