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.
