CATALYST

A catalyst in solid particulate form free from an external carrier material comprising (i) a complex of formula (I) wherein M is zirconium or hafnium; each X is a sigma ligand; L is a divalent bridge selected from -R'2C-, -R'2C-CR'2-, -R'2Si-, -R'2Si-Si R'2-, -R'2 Ge-, wherein each R' is independently a hydrogen atom, C1-20-alkyl, tri(C1-20-alkyl)silyl, C6-20-aryl, C7-20-arylalkyl or C7-20-alkylaryl; R2 is a C1-20-hydrocarbyl radical; R2' is a C1-20-hydrocarbyl radical;R6 is a linear or branched aliphatic C1-20-hydrocarbyl group, SR9or OSR9;R6' is a linear or branched aliphatic C1-20-hydrocarbyl group, SR9'or OR9'; with the proviso that neither R6 or R6' represents a group having a quaternary carbon atom directly attached to the indenyl ring; R9 is a C1-20-hydrocarbyl group;R9' is a C1-20-hydrocarbyl group; Ar is a C6-12-aryl or C5-12-heteroaryl group optionally carrying one or more substituents R8; Ar' is a C6-12-aryl or C5-12-heteroaryl group optionally carrying one or more substituents R8';each R8 is a C1-20-hydrocarbyl group;each R8' is a C1-20 -hydrocarbyl group;wherein at least two of R2 and R2'; R6 and R6'; or Ar and Ar' are the same;and (ii) a cocatalyst comprising a compound of a group 13 metal, e.g. Al or boron.
