    Abstract: A process for the manufacture of poly- alpha -olefins by polymerizing alpha -olefins by means of a catalyst system comprising (1) a titanium-containing component obtained from (1.1) a compound of the formula TiCl3.1/3AlCl3 and (1.2) an organic electron donor, containing phosphorus, nitrogen and/or oxygen atoms, which has been milled with the compound of the formula TiCl3.1/3AlCl3 (1.1), in order to form a complex compound, the milling being carried out without assistants or additives in a vibratory ball mill under specific acceleration conditions and at a temperature which is from 4 DEG to 10 DEG C. below the temperature at which the particles of the material being ground begin to agglomerate, and (2) an aluminum-containing component, in which process the titanium-containing component (1) of the catalyst system used is one which has been treated, after milling and before polymerization, with (i) titanium tetrachloride and (ii) an ether and/or an ester.
