PROCESS TO PREPARE A SOLID CATALYST COMPOSITION

摘要

Solid catalyst composition comprising a polymer matrix (A) and distributed therein a solid catalyst system (B), wherein - the solid catalyst system (B) has a porosity measured according to ASTM 4641 of less than 1.40 ml/g, comprises a transition metal compound of formula (I), LmRnMXq (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 s-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 olefinic 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 - the mol ratio of Al of the cocatalyst (Co) and the transition metal "M" of the transition metal compound [Al/M] is from 100 to 800 mol/mol.
