    Abstract: A PROCESS FOR THE POLYMERIZATION OF OLEFINS WHICH COMPRISES POLYMERIZING OR COPOLYMERIZING OLEFINS IN THE PRESENCE OF A CAALYST CONSISTING ESSENTIALLY OF: (A) A TITANIUM TRICHLORIDE COMPOSITION OBTAINED BY EXTRACING A CRUDE TITNIUM TRICHLORIDE COMPOSITION INCLUDING AN ALUMINUM-CONTAINING INORGANIC SUBSTANCE SUCH CRUDE TITANIUM TRICHLORIDE COMPOSITION BEING PREPARED BY REDUCING TITANIUM TETRACHLORIDE WITH AN ORGANOALUMINUM CHLORIDE EXPRESSED BY THE FOLLOWING FORMULA

    R3-NAICIN

    WHEREIN R IS AN ALKYL GROUP O 1-6 CARBON ATOMS OR AN ARYL GROUP, AND N IS A POSITIVE NUMBER GREATER THAN 0 (ZERO) BUT SMALLER THAN 3, WITH A MIXED SOLVENT COMPOSED OF (1) A MAIN SOLVENT SELECTED FROM THE GROUP CONSISTING OFF SATURATED ALIPHATIC HYDROCARBONS, AROMATIC HYDROCARBONS, HALOGENATED AROMATIC HYDROCARBONS, TRICHLORETHYLENE AND CARBON DISULFIDE AND (II) AN AUXILIARY SOLVENT SELECTED FROM THE GROUP CONSISTING OF OXYGEN-CONTAINING ORGANIC COMPOUNDS NITROGEN-CONTAINING ORGANIC COMPOUNDS, SILICON-CONTAINING ORGANIC COMPOUNDS AND THIOETHETS, AND SEPARATING THE TITANIM TRICHLORIDE COMPOSITION FROM THE EXTRACT; AND (B) AN ORGANOALUMINUM COMPOUND.

    Abstract: CATALYST SYSTEM FOR THE POLYMERIZATION OF OLEFINS CONSISTING OF (1) A POWDERED INORGANIC CARRIER AND, APPLIED THERETO, (2) A ZEIGLER-TYPE CATALYST CONSISTING OF (2,1) A COMPONENT SELECTED FROM THE GROUP CONSISTING OF CHLORIDES, OXYCHLORIDES AND ALKOXYCHLORIDES OF TITANIUM, ZIRCONIUM AND VANADIUM AND (2.2) A COMPONENT SELECTED FROM THE GROUP CONSISTING OF SATURATED METAL ALKYLS, SATURATED METAL ALKOXYALKLS AND SATURATED METAL ALKYL HALIDES OF THE METALS ALUMINUM, MAGESIUM AND ZIND. THE CHARACTERIZING FEATURE OF THE CATALYST SYSTEM OF THE INVENTION IS THAT THE CARRIER (1) HAS BEEN OBTAINED BY HEATING A SUBSTANCE OF THE FORMULA

    ,H MG(SN(OH)6)

    THIS CATALYST SYSTEM IS VERY EFFLICIENT AND ENABLES THE MOLECULAR WEIGHT OF THE POLYMERS TO BE WELL REGUALTED BY MEANS OF HYDROGEN.
