    Abstract: A catalyst system comprises an activated sold support material and having, on its surface, one or more catalytic transition metal complex, wherein the solid support material comprises a core@layered double hydroxide shell material having the formula I TP @ {[Mz+(i -x)M'xy+(OH)2]a+(Xn )a/n»bH2O»c(AMO-solvent)}q (I) wherein T is a solid, porous, inorganic oxide-containing framework material, Mz+ and My+ are independently selected charged metal cations; Mz+ is a metal cation of charge z or a mixture of two or more metal cations each independently having the charge z; M'y+ is a metal cation of charge y or a mixture of two or more metal cations each independently having the charge y; z = 1 or 2; y = 3 or 4; 0 0; q>0; Xn~ is an anion; with n > 0; a = z(1-x) + xy-2; and AMO-solvent is an organic solvent which is completely miscible with water. The catalyst system has use in the polymerisation and/or copolymerisation of at least one olefin for producing a homopolymer and/or copolymer. Also disclosed is a process for preparing a polyolefin homopolymer or a polyolefin copolymer which comprises reacting olefin monomers in the presence of the catalyst system. Preferably, the polyolefin is polyethylene and the olefin monomer is ethylene.
