1. A process for producing a supported olefin polymerization catalyst comprising a compound of a transition metal of Group 3 to 10 of the Periodic Table (IUPAC), comprising suspending a porous particulate support material in a liquid/liquid at least two phase system which comprises a solution of one or more catalyst components in an organic solvent selected from linear, branched or cyclic alkane or alkene, an aromatic hydrocarbon and/or a halogen containing hydrocarbon or a mixture thereof and a solvent immiscible therewith, to impregnate said solution into the pores of said support material, wherein the active transition metal concentration in the support is from 0.001 to 10% by weight of the dry catalyst system, wherein the solution impregnated in said support particles is subjected to solidification to solidify the catalyst components and wherein said immiscible solvent which forms the continuous phase comprises a fluorinated hydrocarbon, a functionalized derivative thereof, or a mixture thereof.
