Abstract: The present invention relates to a novel process for the preparation of Ziegler-Natta catalyst systems containing, as active constituents, a) a titanium-containing solid component which contains titanium, magnesium, halogen and a carboxylic ester and, as cocatalyst, b) an aluminium compound and c) optionally a further electron-donor compound. The invention furthermore relates to Ziegler-Natta catalyst systems obtainable by this process, to the preparation of polymers of propylene with the aid of these catalyst systems, to polymers obtainable by this preparation method, and to films and mouldings made from these polymers.

Abstract: Catalyst systems of the Ziegler-Natta catalyst type, containing, as active constituents, a) a titanium-containing solid component which contains titanium, magnesium, halogen and a carboxylic acid ester, and, as cocatalyst, b) an aluminium compound and c) optionally further electron-donor compounds, characterised in that they contain in the solid component, as the carboxylic acid ester, a diester of a carboxylic acid of the formula Ia or Ib in which R , R , R and R are identical or different and are hydrogen, C1-C15-alkyl, C7-C15-alkylaryl or 5- to 7-membered cycloalkyl, which may itself carry C1- to C10-alkyl groups. These catalyst systems are particularly suitable for the preparation of polypropylene and copolymers of propylene with minor amounts of other alpha , beta -unsaturated olefinic compounds having 2 to 12 carbon atoms.
