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: A process for polymerizing C3-C10-alk-1-enes with the aid of a Ziegler-Natta catalyst system. A titanic solid component, which contains a compound of titanium, magnesium, a halogen and an electron donor compound (I), is first made to react with an aluminium compound and an additional electron donor compound (II). The reaction mixture is then inactivated by reaction with carbon dioxide. The catalyst system thus produced is then used, together with an aluminium compound, to polymerize C3-C10-alk-1-enes at temperatures of between 20 and 150 DEG C and pressures of between 1 and 100 bar, no further quantities of the electron donor compound (II) being needed for said polymerization.
