Abstract

The present invention describes a process of preparing a catalyst for olefin polymerization comprising: (i) treating a magnesium metal with an organohalide along with an internal donor to obtain a reaction mixture having solid component (A); (ii) treating the reaction mixture having solid component (A) with an acyl halide to obtain a reaction mixture having solid component (B); and (iii) treating the reaction mixture having solid component (B) of step (ii) with a transition metal compound to obtain the catalyst. The present invention also relates to a process for preparation of a catalyst system from said catalyst and preparation of a polyolefins from the catalyst system.
