Abstract

The present invention describes a process for preparing catalyst for the polymerization of ethylene consisting essentially of the steps of (i) contacting a magnesium based precursor with a solvent; and (ii) then contacting the magnesium based precursor in the solvent with a transition metal compound to obtain the catalyst, wherein step (ii) is single contact step. The present invention also relates to a process for preparation of a catalyst system and a process of polymerizing and/or copolymerizing of ethylene to obtain a polyethylene using the catalyst.
