Abstract: Process for the preparation of a catalyst being in the form of solid particles comprising the steps of preparing a solution of a complex of a metal which is selected from one of the groups 1 to 3 of the periodic table (IUPAC) and an electron donor by reacting a compound of said metal with said electron donor in an organic liquid reaction medium; adding to said solution solid material obtaining a suspension, said solid material does not comprise catalytically active sites, has a specific surface area below 500 m2/g, and has a mean particle size below 200 nm; combining said suspension at a temperature of at least 50° C. with at least one transition metal compound resulting in a precipitation of said catalyst being in the form of a solid particle, wherein said transition metal compound is selected from one of the groups 4 to 10 of the periodic table (IUPAC) or a compound of actinide or lanthanide; and optionally separating said catalyst; said catalyst being in the form of solid particles, which have a specific surface area of less than 20 m2/g, and contain said solid material.
