Abstract: The invention provides a process for the preparation of a multimodal ethylene polymer in a multistage process in the presence of a catalyst comprising a complex of formula (lx) wherein each X is a sigma donor ligand; each Het is independently a monocyclic or multicyclic heteroaromatic or heterocyclic group containing at least one heteroatom selected from O, N or S; L is a carbon, silicon or germanium based divalent bridge in which one or two backbone atoms link the ligands; M is Ti, Zr or Hf; each R1 is the same or different and is a linear CMO alkyl group, or linear CHO alkoxy, each n is 0 to 3; each R2 is the same or different and is a C1-10 alkyl group, C1-10 alkoxy group or -Si(R)3 group; each R is the same or different and is C1-10 alkyl or phenyl group optionally substituted by 1 to 3 C1-6 alkyl groups; and eachp is 0 to 3;

Abstract: A racemic metallocene complex of formula (I') wherein each X is a sigma donor ligand; L is a carbon, silicon or germanium based divalent bridge in which one or two backbone atoms link the ligands; M is Ti, Zr or Hf; each Het is independently a monocyclic or multicyclic heteroaromatic or heterocyclic group containing at least one heteroatom selected from O, N or S; each R1 is the same or different and is a linear C1-10 alkyl group, or linear C1-10 alkoxy, each n is 0 to 3; each R2 is the same or different and is a -Si(RaRbRc) group; Ra is C1-10 alkyl or phenyl group optionally substituted by 1 to 3 C1-6 alkyl groups; Rb is C1-10 alkyl or phenyl group optionally substituted by 1 to 3 C1-6 alkyl groups; Rc is a phenyl group optionally substituted by 1 to 3 C1-6 alkyl groups; and each p is 1 to 3.

Abstract: This invention relates to a process for making single site catalysts using surfactants free from perfluorinated octanoic acid and perfluorinated octanoic acid related compounds. The invention also relates to the use of such catalysts for the production of polyolefins as well as to the solid catalysts themselves.
