Effect of central metal on activity of the metallocene catalyst supported onmagnesium chloride adduct in ethylene polymerization

In metallocene catalysts, due to their homogeneous nature, heterogenization is important with the aimof mimicking Ziegler–Natta systems. For heterogenization, magnesium chloride adduct was modifiedand mixed with alkyl aluminum compounds; then a metallocene catalyst with an appropriate structurewas supported on it. This supported catalyst was used in the polymerization of ethylene with the helpof triethylaluminum. The polymerization of ethylene was studied at a constant catalyst concentrationand various pressures and temperatures.
