Abstract:
1. Process for the preparation of a catalyst being in the form of solid particles comprising the steps of (a1) preparing a solution (A) of a complex (C) of a metal which is selected from one of the groups 1 to 3 of the periodic table (IUPAC) and an electron donor (E) by reacting a compound (CM) of said metal with said electron donor (E) or a precursor (EP) thereof in an organic liquid reaction medium (OL1); (b1) adding to said solution solid material (SM) obtaining a suspension (S1), said solid material (SM) (c1) combining said suspension (S1) at a temperature of at least 50° C. with at least one transition metal compound (CT) resulting in a precipitation of said catalyst being in the form of a solid particle, wherein said transition metal compound (CT) is selected from one of the groups 4 to 10 of the periodic table (IUPAC) or a compound of actinide or lanthanide; and (d1) optionally separating said catalyst; said catalyst being in the form of solid particles, which
