Abstract
The present invention relates to a procatalyst comprising the compound represented by Formula (A), preferably the Fischer projection of formula (A) as an internal electron donor. The invention also relates to a process for preparing said procatalyst. Furthermore, the invention is directed to a catalyst system for polymerization of olefins comprising the said procatalyst, a co-catalyst and optionally an external electron donor; a process of making polyolefins by contacting at least one olefin with said catalyst system and to polyolefins obtainable by said process. The invention also relates to the use of said procatalyst in the polymerization of olefins. Moreover, the present invention relates to polymers obtained by polymerization using said procatalyst and to the shaped articles of said polymers.
