Process for the preparation of supported olefin polymerization catalyst and process for the preparation of polyethylene having high bulk density

A process for the preparation of a supported olefin polymerization catalyst, in which (a) a metallocene/activator reaction product, a solvent capable of dissolving it, and a porous support are brought into mutual contact, and (b) the solvent is removed, and in which step (a) is carried out so that t...

Zusammenfassung:A process for the preparation of a supported olefin polymerization catalyst, in which (a) a metallocene/activator reaction product, a solvent capable of dissolving it, and a porous support are brought into mutual contact, and (b) the solvent is removed, and in which step (a) is carried out so that the porous support is impregnated with an amount at maximum its pore volume of the metallocene/activator reaction product and solvent.
