    Abstract: The invention relates to the preparation of a titanium-containing catalyst component (1) for Ziegler catalyst systems, in which (1.1) first (1.1.1) an inorganic oxidic support material (I) and (1.1.2) a solution (II) of (IIa) a lower alcohol, (IIb) a titanium trichloride and (IIc) magnesium chloride are combined, forming a dispersion (III), which is evaporated to form an intermediate (IV), and (1.2) then (1.2.1) the product (IV) from (1.1) and (1.2.2) an aluminium component (V) are combined, the resultant product (VI) being the catalyst component (1), characterised in that the aluminium component (V) employed in (1.2) comprises (1.2.2.1) a complex compound of a certain oxacycloalkane carrying no substituents and a certain aluminium compound, and (1.2.2.2) optionally a certain free aluminium compound.

    Abstract: A special process for the preparation of a titanium component for polymerization catalysts of the Ziegler-Natta type, wherein (1) in a first stage (1.1) an alcoholate of the formula Mr(OR)2, where R is lower alkyl and (1.2) a chlorotoluene of the formula where X is chlorine or hydrogen, are milled together in a particular molar ratio in a vibratory ball mill under particular milling conditions, especially a relatively low temperature, in the absence of a diluent, thereafter (2) in a second stage (2.1) the material resulting from stage (1) is brought together with (2.2) titanium tetrachloride in a particular ratio, the batch is kept for some time at an elevated temperature, with constant mixing, and the resulting solid is isolated, excess titanium tetrachloride being separated off, and finally (3) in a third stage (3.1) the solid resulting from stage (2) is again brought together with (3.2) titanium tetrachloride in a particular ratio, the batch is again kept for some time at an elevated temperature, with constant mixing, and the resulting solid, constituting the novel titanium component, is isolated, excess titanium tetrachloride being removed. The novel titanium compound permits the production of polymers of alpha -monoolefins not only in high yield but also with high isotacticity.
