Ziegler-Natta catalysts are a class of catalysts used in the polymerization of olefins, such as ethylene. They are composed of titanium compounds and organoaluminum compounds. These catalysts enable the formation of polymers with high molecular weights and fewer branches, resulting in HDPE with excellent mechanical properties. The development of Ziegler-Natta catalysts revolutionized the plastics industry by making the production of HDPE more efficient and cost-effective.
