A catalyst composition including the compound of Formula I as an internal electron donor, 

Catalyst composition for polymerization of olefins

The present invention relates to a catalyst composition comprising the compound represented by the Fischer projection of formula (I) as an internal electron donor, (I) wherein: R, R, R, R, Rand Rare the same or different and are independently selected from a group consisting of hydrogen, straight, branched and cyclic alkyl and aromatic substituted and unsubstituted hydrocarbyl having 1 to 20 carbon atoms; Ris selected from a group consisting of straight, branched and cyclic alkyl and aromatic substituted and unsubstituted hydrocarbyl having 1 to 20 carbon atoms; and Ris selected from a group consisting of aromatic substituted and unsubstituted hydrocarbyl having 6 to 20 carbon atoms; N is nitrogen atom; O is oxygen atom; and C is carbon atom. 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 cocatalyst and optionally an external electron donor. Furthermore, the present invention relates to a polyolefin obtainable by the process according to the present invention and to the use of the compound of formula (I) as in internal electron donor in catalysts for polymerization of olefins. 

The present invention relates to a catalyst component for polymerization of an olefin comprising a compound represented by the Fischer projection of: wherein Ris substituted or unsubstituted hydrocarbyl having 1 to 20 carbon atoms; Rand Rare different and independently selected from the group consisting of hydrogen, halogen and substituted or unsubstituted hydrocarbyl having 1 to 20 carbon atoms; R-Roptionally containing one or more hetero-atoms replacing one or more carbon atoms, one or more hydrogen atom or both, wherein said hetero-atom is selected from the group consisting of nitrogen, oxygen, sulfur, silicon, phosphorus and halogen; and wherein the compound of Formula (I) is the only internal electron donor in the catalyst component. The present invention also relates to a process for preparing a polymerization catalyst component comprising the steps of i) contacting a compound RMgXwherein Ris aromatic, aliphatic or cyclo-aliphatic group containing 1 to 20 carbon atoms, X is a halide, and z is in a range of larger than 0 and smaller than 2, with an alkoxy- or aryloxy-containing silane compound to give a first intermediate reaction product; ii) contacting the first intermediate reaction product with at least one activating compound selected from the group formed by internal electron donors and compounds of formula M(OR)(R), wherein M can be Ti, Zr, Hf, Al or Si, each Rand R, independently, represent an alkyl, alkenyl or aryl group, v is the valency of M and w is smaller than v and iii) contacting the second intermediate reaction product with a halogen-containing Ti-compound and an internal electron donor represented by the Fischer projection of formula (I); and optionally with at least one compound selected from a group comprising a monoester, a diester and a 1,3-diether.
