Abstract

Polyethylene of molecular weight 50,000-750,000 is produced from ethylene by means of a catalyst prepared by mixing at 20-80 DEG C. 1-1,5 mols of dialkyl aluminium monochloride (preferably Et2AlCl) with 1 mol. TiCl4 for a period (e.g. at least 24 hours) sufficient to ensure that the mixture contains no TiCl4. Optional additions to the reaction mixture, per kg of catalyst, are (a) 2-200 1,02; and (b) 1-10 gram-mols of an alcohol. Supplementary portions of dialkyl aluminium monochloride may also be used. In the example, polymerization was carried out continuously, using as reaction medium a C7-10 hydrocarbon fraction, formed in the hydrogenation of CO, which had been purified by hydrogenation over Ni, followed by intensive drying and treatment with said TiCl3. Specifications 824,198 and 875,073 are referred to.
