Application of Ziegler-Nata Catalysts in the Synthesis of Polyolefin

Discovering ziegler-nata catalyst, karl ziegler had a great impact on the development of the chemical industry. since then, important changes have been made in the method of production and use of this catalyst. more active and functional catalysts have been developed to produce different products. in 1950, while working on the synthesis of olefins using the catalytic reaction of triethyl aluminum, karl ziegler accidentally discovered that due to the presence of nickel in the reaction vessel, instead of the usual wax-like product, the reaction product was exclusively 1-butene, indicating that nickel catalyzed the hydrogen removal reaction. after ziegler's discovery, triethyl aluminum was used with a wide range of intermediate metals, and after many experiments, titanium tetrachloride became the most active compound. the discovery of karl ziegler and her colleagues in 1953 was one of the most important discoveries in the field of polymer synthesis at that time, leading to a remarkable scientific and industrial breakthrough in the production of polyolefin.
