The present invention relates to a solid Ziegler-Natta catalyst component comprising transition metal compound of Group 4 to 6, and a polymeric internal organic compound, preferably selected from linear or branched polyalkyleneimines or isomers or mixtures therefrom. The invention relates further to the use of said polymeric internal organic compound as internal electron donor in a solid Ziegler-Natta catalyst component, a catalyst comprising said solid Ziegler-Natta catalyst component and a cocatalyst, and use of said catalyst in producing C 2 to C 6 olefin (co)polymers. |
