Abstract: The invention relates to the polymerisation of alpha -monoolefins by means of a catalyst system comprising (1) a titanium component, (2) an alkylaluminium compound and (3) a cocatalyst, characterised in that a novel, modified titanium component (1) is provided for this purpose; it is obtained by first (1.1) preparing a first intermediate from (1.1.1) titanium tetrachloride, (1.1.2) a modifier comprising (1.1.2.1) a titanic acid ester and (1.1.2.2) a phthaloyl dichloride, and (1.1.3) magnesium alcoholate, then (1.2) preparing a second intermediate from (1.2.1) titanium tetrachloride, (1.2.2) the intermediate from (1.1) and, if desired, (1.2.3) a phthaloyl dichloride as further modifier, and finally (1.3) preparing the titanium component (1) from (1.3.1) titanium tetrachloride and (1.3.2) the intermediate from (1.2).

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 Mg(OR)2, where R is lower alkyl, and (1.2) benzoyl chloride 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 at an elevated temperature for some time, with constant mixing, and the resulting solid is isolated, excess titanium tetrachloride being removed, 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 at an elevated temperature for some time, with constant mixing, and the resulting solid, constituting the novel titanium component, is isolated, excess titanium tetrachloride being removed. The novel titanium component permits the preparation of alpha -monoolefin polymers in high yield and with high isotacticity.
