Abstract: A process for the manufacture of a titanium-containing component of a catalyst for the Ziegler-Natta polymerization of alpha -monoolefins, by (a) milling a titanium-containing compound of the general formula TiCl3.nAlCl3 (where n is a number from 0.01 to 1) with (b) an ether of a particular type or an ester of a particular type, wherein (1) a vibratory ball mill giving a relatively high milling acceleration is used, (2) the mill is first charged with the titanium-containing compound (a), after which it may or may not be run for a certain period, thereafter (3) while milling, the amount of the ether or ester (b) which corresponds to a particular molar ratio of aluminum in the titanium-containing compound (a) to ether or ester (b) is added continuously or in small portions, then (4) the batch is milled for a certain period, after which (5) the product obtained from stage (4) may or may not be washed with a hydrocarbon and dried, and following which (6) the product obtained from stage (4) or (5) may or may not be milled for a certain period at a low temperature, next (7) the product obtained from stage (4), (5) or (6) is brought together with a liquid silicon compound of a particular type or a liquid tin compound of a particular type (these compounds acting as promoters) and the batch is left for a certain period and is then separated into a solid-phase product and into a liquid-phase product, and thereafter (8) the solid-phase product obtained from stage (7) is washed with a hydrocarbon or with one of the promoters mentioned under (7) and is dried, following which (9) the product obtained from stage (8) may or may not be milled for a certain period at a low temperature. Using the titanium-containing catalyst components thus obtainable makes it possible to produce polymers, having a high stereoregularity, in high specific yields.

Abstract: A process for the manufacture of a titanium-containing component of a catalyst for the polymerization of monoolefins by the Ziegler-Natta method by milling (a) a particular titanium-containing compound, viz. a titanium trichloride/aluminum trichloride complex and (b) a particular ester with one another, in which process (1) a vibratory ball mill producing a particular milling acceleration is used, (2) the mill is first charged with the titanium-containing compound (a) and may or may not then be run for some time in the absence of diluents, (3) while milling, the ester (b) is added at a particular rate, continuously or in small portions, and in the absence of diluents, thereafter (4) the grist is brought to an elevated temperature, while milling, and is kept at this temperature until from 5 to 85% of the aluminum trichloride originally present in a bonded form in the titanium-containing compound (a) have been eliminated from the said compound (a), after which (5) if appropriate, the product obtained in accordance with (4) is washed with a hydrocarbon and dried, and then (6) the product obtained in accordance with (4) or in accordance with (5) is milled for a certain length of time at a low temperature in the absence of a diluent. Polyolefins of high stereoregularity can be obtained in a high specific yield by means of the catalyst component manufactured according to the invention.
