Abstract

In catalyst systems of the Ziegler-Natta type comprising as active constituents PA1 a) a titanium-containing solid component which is obtained by reacting a compound of titanium with a compound of magnesium, a halogen, an inorganic oxide as support, a C.sub.1 -C.sub.8 -alkanol and a carboxylic ester as electron donor compound, and also as cocatalyst, PA1 b) an aluminum compound and PA1 c) if desired, a further electron donor compound, the reaction of the individual components for preparing the titanium-containing solid component a) is carried out in the presence of an aromatic hydrocarbon as solvent.
