[54] CATALYST COMPOSITION FOR POLYMERIZATION OF OLEFINS
[57] Abstract: The present invention relates to a catalyst composition comprising a monoester, the compound represented by formula (I) as an internal electron donor, and optionally an additional internal electron donor selected from a group consisting of diesters and diethers, Formula (I)wherein:R1, R2, R3, R4, R5 and R6 are the same or different and are independently selected from the group consisting of hydrogen, straight, branched and cyclic alkyl having at most 20 carbon atoms and aromatic substituted and unsubstituted hydrocarbyl having 6 to 20 carbon atoms;R7 is selected from the group consisting of straight, branched and cyclic alkyl having at most 20 carbon atoms and aromatic substituted and unsubstituted hydrocarbyl having 6 to 20 carbon atoms; and R8 is selected from the group consisting of aromatic substituted and unsubstituted hydrocarbyl having 6 to 20 carbon atoms.The present invention also relates to a process for preparing said polymerization catalyst composition and to a polymerization catalyst system comprising said catalyst composition, a co-catalyst and optionally an external electron donor. Furthermore, the present invention relates to use of said catalyst composition for polymerization of olefins.
