    Abstract: A catalyst for polymerisation of ethylene and other alphaolefins comprising a combination of a metallorganic derivative of the elements belonging to groups IA, IIB and IIIB of the periodic system and a supported halide of a transition metal of group IVB and VB of the periodic system, the said supported halide being obtained by reaction of the halide with the solid product resulting from suitable deposition of metallic aluminium on an activated alumina and/or silica and/or silico-aluminate.

    Abstract: Solid catalysts which can be used for the polymerization of olefins, essentially comprising compounds of magnesium and metals selected from the transition metals of sub-groups IVa, Va and VIa of the periodic table of elements, said catalysts being produced in accordance with a method which comprises in a first stage the preparation of a solid compound of magnesium and a transition metal by the reaction of organo-magnesium compounds, monohalogenated hydrocarbons and halogenated and/or organic derivatives of said transition metal taken in a state of valency at least equal to four, then, in a second stage, bringing the solid magnesium and transition metal compound resulting from the preceding reaction into contact with an oxidizing compound.

    Abstract: OLEFINES ARE POLYMERIZED IN THE PRESENCE OF HYDROGEN AS A MOLCULAR WEIGHT CONTROL AGENT WITH A ZIEGLER-TYPE CATALYST COMPOSITION COMPRISING A MIXTURE OF A COMPOUND OF VANADIUM AND A REDUCING AGENT WHICH IS AN ORGANOALUMINUM COMPOUND AND AN ALKALYALUMINUM ALKOXIDE, SAID COMPOSITION BEING PREPARED BY COMBINING SAID COMPONENTS IN SUCH ORDER THAT SAID ALUMINUM ALKOXIDE IS PRESENT PRIOR TO COMBINATION OF SAID VANADIUM COMPOUND WITH SAID ORGANOALUMINUM COMPOUND. THE CATALYST SO PREPARED ENHANCES THE ABILITY OF HYDROGEN TO ACT AS A CHAIN-TRANSFER AGENT IN CONTROLLING MOLECULAR WEIGHT, THAT IS, LOWER MOLECULAR WEIGHT POLYMERS CAN BE PRODUCED AT A GIVEN HYDROGEN CONCENTRATION OR LESSER AMOUNTS OF HYDROGEN ARE REQUIRED TO PRODUCE POLYMMER PRODUCTS HAVING SPECIFIED MOLECULAR WEIGHTS.

    Abstract: A FIBROUS COPPER OXIDE CATALYST FOR RENDERING CARBON MONOXIDE AND RESIDUAL HYDROCARBONS CONTAINED IN THE EXHAUST GAS OF INTERNAL COMBUSTION ENGINES HARMLESS IS MANUFACTURED BY THE STEPS OF PREPARING A WEB OR THE LIKE MADE OF A FINE WIRE OF AN IRON BASE HEAT RESISTANT ALLOY CONTAINING NICKEL AND/OR CHROMIUM, APPLYING A MIXTURE CONSISTING OF COPPER OXIDE, METAL HALIDE AND CARBONACEOUS SUBSTANCE UPON THE SAID WEB TO FORM A LAYER OF THE MIXTURE HAVING A UNIFORM THICKNESS, HEATING THE RESULTING ASSEMBLY IN NON-OXIDIZING ATMOSPHERE AT A TEMPERATURE OF ABOUT 750*C. TO FORM FIBROUS COPPER OR FIBROUS COPPER CONTAINING A SMALL QUANTITY OF ANOTHER METAL, THE FIBROUS COPPER BEING FIRMLY BONDED TO THE SAID WEB, AND OXIDIZING THE RESULTANT COMPOSITE BODY TO FORM A FIBROUS COPPER OXIDE OR AN OXIDE OF A FIBROUS COPPER BASE ALLOY.
