    Abstract: Catalyst systems of the Ziegler-Natta type containing, as active constituents a) a titanium-containing solid component containing titanium, magnesium, halogen and a carboxylic ester (carboxylate) as electron-donor compound, and, as catalyst b) an aluminium compound and c) optionally a further electron-donor compound, where a compound of the formula I Rm1A1 - (OCOR )m2 (I> in which R and R are identical or different and are each a hydrogen radical or a C1-C8 alkyl radical and m1 and m2 are each the number 1 or 2 and they add up to the number 3, is used during preactivation of the titanium-containing component a) with the cocatalyst as aluminium compound b).

    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, as the carboxylic acid ester in the solid component a), an ester of a benzophenone-2-carboxylic acid of the formula I in which R is a hydrogen atom, a C1-C15-alkyl group or a halogen atom. 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.

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.
