Abstract: The present invention describes a process for preparation of catalyst component comprising contacting magnesium based precursor along with an internal donor based on phenylene dioates with an acyl halides in a solvent to obtain a solid precatalyst component; and contacting the solid precatalyst component with transition metal compound to obtain the catalyst component. The present invention also relates to a process for preparation of a catalyst system from said catalyst component and preparation of a polyolefins having free flowing characteristics with bulk densities (BD) of at least about 0.3 g/cc from the catalyst system.
