    Abstract: A process for the manufacture of a modified titanium-containing component of a Ziegler-Natta catalyst for the polymerization of C3-6 .alpha.-monoolefins, wherein a specific titanium-containing compound and a specific phosphorus-containing compound are dry-milled at a specific grinding acceleration in a vibratory ball mill, The characteristic feature of the process of the invention is that a mill is used which has a specific useful volume and the mill is initially charged with a specific amount of the titanium-containing compound, which is milled at a low temperature while the phosphoruscontaining compound is gradually added, whereupon milling is continued while the temperature of the process material is gradually raised to a specific value and maintained at said value for a specific period of time, whereupon, if desired, milling is again continued at a lower temperature for a specific period of time. In this manner, modified titaniumcontaining components are obtained which in the polymerization process produce highly reproducible yields of polymer.

    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.

    Abstract: A process for the manufacture of a modified titanium-contain-ing component or a catalyst for the polymerization of .alpha.-mono-olefins by the Ziegler-Natta method wherein (a) a compound containing titanium and (b) a compound containing phosphorus are ground dry in a vibratory ball mill. It is characterisrtic of the process that (1) a mill Or relatively large useful volume is employed, (2) the mill is first charged with the compound (a) containing titanium, (3) wilst grinding the material at a low temperature, the compound (b) containing phosphorus is added gradually, thereafter (4) the materials is gradually brought to a higher temperature, whilst continuing the grinding, and is kept at about this temperature for a prolonged period, then (5) a finely particulate 1-alkene polymer having a particular glass transition temperature and a particular intrinsic viscostiy is added to the material and finally (6) the material is kept at a low temperature for a prolonged period, whilst continuing the grinding.
