| titleOfInvention | Process for making polypropylene using a selectivity control agent and an activity limiting agent |
| abstract | The invention relates to a process for the production of a propylene homopolymer or a propylene-ethylene copolymer comprising the step of polymerizing propylene and optional ethylene comonomers in the presence of a catalyst to obtain the propylene homopolymer or the propylene-ethylene copolymer, wherein said catalyst is obtainable by a process comprising the steps of A) providing a Ziegler-Natta procatalyst comprising 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 B) contacting said Ziegler-Natta procatalyst obtained in step A) with a cocatalyst and a Selectivity Control Agent (SCA) in combination with an Activity Limiting Agent (ALA) to obtain said catalyst |
