Solid catalyst composition comprising a polymer matrix (A) and distributed therein a solid catalyst system (B), wherein (a) the solid catalyst system (B) comprises • a transition metal compound of formula (I) L m R n MX q , (I) wherein "M" is a transition metal of anyone of the groups 3 to 10 of the periodic table (IUPAC), each "X" is independently a monovalent anionic σ-ligand, each "L" is independently an organic ligand which coordinates to the transition metal (M), "R" is a bridging group linking two organic ligands (L), said organic ligands (L) and said bridging groups (R) do not comprise polymerizable olefϊnic groups, "m" is 2 or 3, "n" is 0, 1 or 2, "q" is 1, 2 or 3, m+q is equal to the valency of the transition metal (M), and • a cocatalyst (Co) comprising a compound of Al, and (b) the polymer matrix (A) is not covalent bonded to anyone of the organic ligands (L) and/or to anyone of the bridging groups (R) of the transition metal compound. |
