    Abstract: THIS INVENTION PROVIDES A PROCESS FOR HOMOPOLYMERIZING OR COPOLYMERIZINAG ETHYLENE IN THE PRESENCE OF MIXED CATALYSTS COMPRISING AS COMPONENT A THE REACTION PRODUCT OF 0.1 TO 1.0 PART BY WEIGHT OF MG(OH)2, 1 PART BY WEIGHT OF TI(O-ISOC3H7)4 AND 0.4 TO 0.9 PART BY WEIGHT OF TICL4 AND AS COMPONENT B AN ORGANO-ALUMINUM CONPOUND. UNDER A PRESSURE OF UP TO 20 ATMOSPHERES THE POLYMER YIELDS ARE SO HIGH PER UNIT OF CATALYST THAT THE RESIDUES THEREOF NEED NOT BE REMOVED. BY VARIATION OF THE PROPORTIONS OF MG(OH)2 TO TITANIUM COMPOUNDS POLYMERS HAVING DENSITIES IN THE INDUSTRIALLY INTERESTING RANGE OF FROM 0.952 TO 0.962 G/CC. CAN BE OBTAINED.

    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 halogen-free magnesium compounds containing 0.1 to 2 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: 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 gramatom 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: PROCESS FOR HOMO- AND COPOLYMERIZING OLEFINS IN THE PRESENCE OF A MIXED CATALYST COMPRISING, AS COMPONENT A, A REACTION PRODUCT OF MAGNESIUM ALCOHOLATES WITH TETRAVALENT HALOGENATED TITANIUM COMPOUNDS AND, AS COMPONENT B, ORGANO-ALUMINUM COMPOUNDS. ALREADY UNDER A PRESSURE OF LESS THAN 20 ATMOSPHERES THE YIELDS PER CATALYST OBTAINED ARE SO HIGH THAT THE REMAINDERS OF CATALYST NEED NOT BE REMOVED FROM THE POLYMER. OPTIONALLY, PRODUCTS CAN ALSO BE PREPARED WHICH HAVE A VERY NARROW MOLECULAR WEIGHT DISTRIBUTION AND VERY GOOD COLOR AND CORROSION VALUES.
