22772-1013 ABSTRACT A process is disclosed for preparing a titanium catalyst component useful for homopolymerizing 1-alkenes and for copolymerizing 1-alkenes with each other and/or with ethylene, consisting essentially in grinding a titanium halide compound/electron-donor complex with a magnesium aluminum halide obtained by precipitation from an organic solvent. In the process the ground product is first washed with a washing liquid containing one or a mixture of solvents in which the complex of the aluminum halide concerned and the electron-donor concerned is at least partially soluble, and at least one alcohol, the molar ratio between alcohol and titanium in the ground product ranging between 50:1 and 1:20, and then the washed product is exposed to a liquid titanium halide compound. With this procedure, it is possible to obtain a titanium component which imparts to the polymerization catalyst an excellent stereospecificity along with a very high activity, and with which it is possible to obtain polymers, e.g. polypropylene, with a very low halogen content, a very low titanium content, and an excellent powder morphology and bulk density. 3476 CA
