    Abstract: Manufacture of particulate polyethylene by polymerizing ethylene in an agitated bed of dry particulate polyethylene by means of a catalyst system comprising (1) a particulate inorganic carrier and (2) a Ziegler catalyst applied to said carrier. The catalyst system is used in the form of an intimate mixture of the catalyst system with a particulate ethylene polymer which does not soften at the polymerization temperature used, the particles in said mixture being coated with a saturated hydrocarbon wax which is solid at 30*C but liquid at the polymerization temperature used. This process makes it possible to obtain particulate polyethylene having a desirable particle size distribution.

    Abstract: Manufacture of particulate polyethylene by polymerizing ethylene in an agitated bed of dry particulate polyethylene by means of a catalyst system comprising (1) a particulate inorganic carrier and (2) a Ziegler catalyst applied to said carrier. The catalyst system is used in the form of an intimate mixture of the catalyst system with a particulate ethylene polymer having a softening point above the polymerization temperature used, the particles in said mixture being coated with an inert organic material which is solid at 30*C but liquid at the polymerization temperature used. This process makes it possible to obtain particulate polyethylene having a desirable particle size distribution.

    Abstract: CATALYST SYSTEM FOR THE POLYMERIZATION OF OLEFINS CONSISTING OF (1) A POWDERED INORGANIC CARRIER AND, APPLIED THERETO, (2) A ZEIGLER-TYPE CATALYST CONSISTING OF (2,1) A COMPONENT SELECTED FROM THE GROUP CONSISTING OF CHLORIDES, OXYCHLORIDES AND ALKOXYCHLORIDES OF TITANIUM, ZIRCONIUM AND VANADIUM AND (2.2) A COMPONENT SELECTED FROM THE GROUP CONSISTING OF SATURATED METAL ALKYLS, SATURATED METAL ALKOXYALKLS AND SATURATED METAL ALKYL HALIDES OF THE METALS ALUMINUM, MAGESIUM AND ZIND. THE CHARACTERIZING FEATURE OF THE CATALYST SYSTEM OF THE INVENTION IS THAT THE CARRIER (1) HAS BEEN OBTAINED BY HEATING A SUBSTANCE OF THE FORMULA

    ,H MG(SN(OH)6)

    THIS CATALYST SYSTEM IS VERY EFFLICIENT AND ENABLES THE MOLECULAR WEIGHT OF THE POLYMERS TO BE WELL REGUALTED BY MEANS OF HYDROGEN.

    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.
