237 Ziegler-Natta Polymerization
Ziegler-Natta polymerization is a method of vinyl polymerization using a Ziegler-Natta (ZA) catalyst such as a mixture of titanium chloride (or related compounds, like oxovanadium chloride) with triethylaluminum (or trimethylaluminum). Other components are often added, such as magnesium chloride, to modify the catalyst and improve performance.
A ZN catalyst is named after two chemists: Karl Ziegler and Giulio Natta. In 1953, German chemist Karl Ziegler and Italian chemist Giulio Natta discovered a catalytic system able to polymerize α-olefins with high linearity and stereoselectivity. The 1963 Nobel Prize in Chemistry was awarded to Karl Ziegler for his discovery of the first ...
