Abstract: A process for preparing a procatalyst for polymerization of olefins, comprising contacting a magnesium-containing support with a halogen-containing titanium compound, a first internal electron donor represented by Formula A, a second internal electron donor represented by Formula B, and an activator; wherein the molar ratio of the first internal donor to the second internal donor is between 0.01 and 0.7; wherein in Formula A each R80 group is independently a substituted or unsubstituted aromatic group; and R81, R82, R83, R84, R85, R86 and R87 are each independently selected from a hydrogen or a hydrocarbyl group; wherein in Formula B R51 and R52 are each independently selected from a hydrogen or a hydrocarbyl group; and R53 and R54 are each independently selected from hydrogen, a halide or a hydrocarbyl group.

Abstract: A process for preparing a procatalyst for polymerization of olefins, comprising contacting a magnesium-containing support with a halogen-containing titanium compound, and an internal electron donor according to Formula (I), said process comprising the steps of: i) contacting a compound R4zMgX42-z with an alkoxy- or aryloxy-containing silane compound to give a first intermediate reaction product, being a solid Mg(OR1)xX12-x, ii) optionally contacting the solid Mg(OR1)xX12-x obtained in step ii) with at least one activating compound selected from the group formed by activating electron donors and metal alkoxide compounds of formula M1(OR2)v-w(OR3)w or M2(OR2)v-w(R3)w, to obtain a second intermediate product; iii) contacting the first or second intermediate reaction product, obtained respectively in step i) or ii), with a halogen-containing Ti-compound and said compound represented Formula (I), as the internal electron donor.
