Abstract

1. A process for the production of a pulverulent polyolefin by polymerisation of ethylene or copolymerisation of ethylene with propylene and/or 1-butene in the gas phase at a pressure of 10 to 100 bar, preferably 25 to 50 bar, at a temperature of 50 to 110 degrees C using a Ziegler catalyst comprising a vanadium component and an organo-aluminium component, optionally in the presence of hydrogen, characterised in that a catalyst comprising a mixture of the following ingredients is used : 1) a vanadium component which has been obtained by reaction of, on the one hand, a mixture of vanadium (V) chloride and vanadium (V) alcoholate in a molar ratio of 1 : 2 to 2 : 1 or a reaction product of vanadium (V) chloride and ethanol, 1-propanol or 1-butanol in a molar ratio of 1 : 2 to 1 : 1 and, on the other hand, ethylaluminium dichloride, diethylaluminium chloride, isobutylaluminium dichloride and/or diisobutylaluminium chloride, the reaction being carried out at a molar ratio V : Al of 1 : 3 to 1 : 1 in an inert solvent whilst stirring with a specific stirring power of 1 to 20,000 watts/m**3 , preferably 1 to 5,000 watts/m**3 , followed by separation of the resulting solids, 2) a calcined, particulate silica xerogel in a weight ratio, based on the vanadium component, of 0.5 : 1 to 10 : 1, mixed with the vanadium component, 3) a flowable, pulverulent polyolefin of average particle diameter up to 1,000 mu m in an amount of 0.5 to 3.0 g per mg of the vanadium component, calculated as vanadium pentoxide, and 4) an organoaluminium compound of the general formula Rn AIX3-n in which R is a saturated hydrocarbon radical of 2 to 20 carbon atoms, X is a halogen atom and n is a number from 1 to 3, or a reaction product of an aluminium trialkyl or a dialkyl- aluminium hydride with a 1,3-diolefin, in an amount of 0.1 to 1.0 millimol per g of pulverulent polyolefin.
