Polymerization Catalysts

The Zieglar-Natta catalyst discovered in 1953 made possible the synthesis of high-density polyethylene. Later, transition metal catalysts such as metallocene were developed for polyolefin synthesis. Transition metal carbene complexes were used as catalysts for ring-opening metathesis polymerization in Nobel Prize-winning work in 2005.
This section also includes catalysts for Kumada-Tamao-Corriu cross coupling for polymer synthesis.
