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.
