Genesis of MgCl2-based Ziegler-Natta Catalysts as Probed with Operando Spectroscopy [PDF]

, 2018
Ziegler‐Natta catalysts for olefin polymerization are intrinsically complex multi‐component systems. The genesis of the active sites involves several simultaneous and sequential steps, making the individual steps and interconnections difficult to be ...

The Effect of a Ziegler-Natta Catalyst and the Polymerization Parameters on the Basic Properties of Polyethylene

, 2007
In our article, some of the basic correlations concerning the polymerization behaviour of a Ziegler-Natta catalyst are presented. We have examined a general, commercial MgCl2 supported catalyst, the effect of the main polymerization parameters, such as ...
