Ziegler-Nattanoun

Chemistry.
  1. 1965–
    Used attributively to designate any catalyst of the class including the Ziegler catalyst, consisting in general of a transition metal halide and a non-transition metal organic derivative, and used with any olefin monomer. So Ziegler-Natta catalysis.
    1. 1965
      Whereas the ionic catalysts appear to be capable of general use with any unsaturated molecule,..Ziegler-Natta catalysts are usually employed in the polymerization of olefinic hydrocarbons—notably, ethylene and proplyene.

    2. 1974
      The Ziegler-Natta catalysts include many mixtures of halides of transition metals, especially titanium, chromium, vanadium, and zirconium, with organic derivatives of nontransition metals, particularly alkyl aluminium compounds.

    3. 1980
      It has been suggested that Ziegler-Natta catalysis may involve metal-carbene formation.
