    Abstract: A process for the preparation of a solid olefin polymerisation catalyst or a solid olefin polymerisation catalyst component comprising the steps of: (a)forming a liquid/liquid emulsion of (i) a first organic liquid comprising at least one olefin polymerization catalyst component and (ii) an optionally halogenated hydrocarbon liquid immiscible therewith; where the first organic liquid forms the dispersed phase and the optionally halogenated hydrocarbon liquid forms the continuous phase of the liquid/liquid emulsion and wherein the dispersed phase forms droplets in the continuous phase; and (b)transforming the droplets of the dispersed phase to solid particulate particles comprising said at least one olefin polymerization catalyst component, wherein the liquid/liquid emulsion is stabilized with a solid particulate stabilizer

    Abstract: The present invention relates to a process for producing solid Ziegler-Natta catalyst component in the form of solid particles having a median particle size (D50 vol ) of 5 to 500 µm the process comprising steps I. providing a solution of a mixture of Group 2 metal compounds of i) a solution of a Group 2 metal dihalide and ii) at least one Group 2 metal alkoxide of the Periodic Table (IUPAC, Nomenclature of Inorganic Chemistry, 2005) II. contacting the solution of the mixture of Group 2 metal compounds of step I with a compound in a liquid form of a transition metal of Group 4 to 10, or of a lanthanide or actinide, preferably a transition metal of Group 4 to 6 of Periodic Table (IUPAC, Nomenclature of Inorganic Chemistry, 2005), and III. recovering the solid catalyst component, wherein the solution of a Group 2 metal dihalide i) is obtained by dissolving a solid Group 2 metal dihalide in an alcohol comprising at least a monohydric alcohol of formula ROH, where R is selected from hydrocarbyl of 3 to 16 C atoms, and wherein the amount of Group 2 metal originating from Group 2 metal dihalide in the solution of the mixture of Group 2 metal compounds is in the range of 5 to 90 mol-%. The invention further relates to a catalyst comprising the catalyst component and use thereof in olefin polymerisation process.
