Abstract: A process for the production of a propylene homopolymer or a propylene-ethylene copolymer includes polymerizing propylene and optional ethylene comonomers in the presence of a catalyst, wherein the catalyst is obtainable by a process of A) providing a Ziegler-Natta procatalyst including contacting a magnesium-containing support with i) a halogen-containing titanium compound, ii) ethylbenzoate as an activator, iii) and as internal donor an aminobenzoate compound according to formula B preferably 4-[benzoyl(methyl)amino]pentan-2-yl benzoate (AB); and B) contacting the Ziegler-Natta procatalyst obtained in step A) with a co-catalyst and a Selectivity Control Agent (SCA) in combination with an Activity Limiting Agent (ALA) to obtain the catalyst.
