Abstract

A novel process for the preparation of Ziegler-Natta catalyst systems containing, as active components, PA1 a) a titanium-containing solid component which contains titanium, magnesium, halogen and a carboxylic ester and, as a cocatalyst, PA1 b) an aluminum compound and PA1 c) if required, a further electron donor is described. Ziegler-Natta catalyst systems which are obtainable by this process, the preparation of polymers of propylene with the aid of these catalyst systems, the polymers obtainable thereby and films and moldings of these polymers are also described.
