Abstract: The present invention provides a process for preparation of a solid titanium catalyst component for use as pro-catalyst for a Ziegler-Natta catalyst system. The solid titanium catalyst component comprises a combination of 15 to 20 wt% of a magnesium moiety, 1.0 to 6.0 wt% of a titanium moiety and 5.0 to 20 wt% of an internal donor, said solid titanium catalyst component has an average particle size in the range of 1 to 100 µm, characterized by a three point particle size distribution of D10 in the range of 1 to 10 µm; D50 in the range of to 25 µm and D90 in the range of 15 to 50 µm. The present invention also provides a 15 Ziegler-Natta catalyst system comprising the solid titanium catalyst component and the method of polymerizing and/or copolymerizing olefins by using the Ziegler-Natta catalyst system.
