    IPC: C08F110/06

    Abstract: The present invention relates to a procatalyst comprising the compound represented by formula A as an internal electron donor, wherein: R81, R82, R83, R84, R85, and R86 are the same or different and are independently selected from a group consisting of hydrogen or a straight, branched and cyclic hydrocarbyl group, selected from alkyl, alkenyl, aryl, aralkyl or alkylaryl groups, and one or more combinations thereof, preferably having 1 to 20 carbon atoms; R87 is a hydrogen or a linear, branched or cyclic hydrocarbyl group, selected from alkyl, alkenyl, aryl, aralkyl, alkoxycarbonyl or alkylaryl groups, and one or more combinations thereof, preferably having from 1 to 20 carbon atoms; and each R80 group is independently a linear, branched or cyclic hydrocarbyl group selected from alkyl, alkenyl, aryl, aralkyl, or alkylaryl groups, and one or more combinations thereof, preferably having from 1 to 30 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 procatalyst and to a polymerization catalyst system comprising said procatalyst, 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 A as in internal electron donor in catalysts for polymerization of olefins.
