    Abstract: The invention provides a process for homopolymerizing or copolymerizing ethylene in the presence of mixed catalysts comprising as component A the reaction products of specific tetravalent titanium compounds with chlorine-containing magnesium compounds containing at least 1.5 moles of OH groups per gram-atom of magnesium and as component B an organo-aluminum compound. Under a pressure below 20 atmospheres the yields are so high per unit of catalyst that the residues thereof need not be removed from the polymer. It is possible to produce polymers having a very narrow distribution of molecular weight and very good color and corrosion values.

    Abstract: 1,155,478. Polymerizing ethylene with Zieglertype catalysts. FARBWERKE HOECHST A.G. 9 Aug., 1967 [9 Aug., 1966], No. 36518/67. Heading C3P. Olefin polymers are made by polymerizing ethylene alone or in admixture with up to 10%, of a higher alpha-olefin having 3 to 15 carbon atoms in solution, suspension, or the gaseous phase, at a temperature in the range of 20‹ to 250‹ C., in presence of hydrogen, and under a pressure up to 10 atmospheres and in the presence of as catalyst a mixture of from 0À05 to 0À3 millimole of a trivalent chlorine-containing compound per litre of dispersing agent or solvent, or per half litre of reaction volume, if the polymerization is carried out in the gaseous phase, and an organo-aluminium compound in amount corresponding to from 0À1 to 3À0 millimoles of aluminium equivalent per litre of dispersing agent, solvent, or reaction volume. The organoaluminium compound is selected from, (a) a compound of the formula AlR 1 3 where R 1 represents a C 4 to C 40 hydrocarbon radical or (b) a reaction product of a trialkylaluminium compound or an alkylaluminium hydride with a diolefin having 4 to 20 carbon atoms, e.g. triisobutyl Al and isoprene (polymeric isoprenyl aluminium). The trivalent chlorine-containing Ti-compound is preferably obtained by reducing a compound of the formula Ti(OR) 4-n Cl n where n is 1 to 4, and R represents a C 2 to C 8 hydrocarbon radical, with an alkyl Al sesquichloride, and/or a dialkyl Al monochloride, and/or isoprenyl Al at a temperature in the range of - 60‹ to +70‹C., and if desired heat-treating and washing the product. The monomers polymerized are purified with a copper catalyst. Exemplified polymers are polyethylene, and a copolymer of ethylene and butene-1.
