Alkene polymerization Ziegler-Natta catalysis and metallocene catalysts 

Epitaxial growth of a crystal on a substrate crystal is such 

Surface site with vacant coordination site 

Propene polymerization by the Ziegler-Natta process can be summarized as follows. 

Comment on the type of polymer produced and the need for selectivity for this form of polypropene. 

The 1963 the Nobel Prize in Chemistry was awarded to Karl Ziegler and Giulio Natta for their discoveries in the field of the chemistry and technology of high polymers . The polymerization of alkenes by heterogeneous Ziegler-Natta catalysis is of vast importance to the polymer industry. In 

Ziegler discovered that, in the presence of certain heterogeneous catalysts, ethene was polymerized to high-molecular-mass polyethene at relatively low pressures. In
