Abstract: A catalyst system suitable for preparing substantially terminally unsaturated atactic polymers or copolymers of &agr;-olefins having a number average molecular weight in the range 300-500,000 comprises (A) a metallocene complex and (B) a cocatalyst comprising (i) a Group III Metal alkyl compound and (ii) a triaryl boron compound. Preferred metallocenes are those having alkyl ligands on the metal atom. The preferred Group III metal alkyl compound is triisobutyl aluminum and the preferred triaryl boron compounds is tris(pentafluorophenyl)boron.

Abstract: Catalyst system suitable for preparing substantially terminally unsaturated atactic polymers or copolymers of &agr;-olefins having a molecular weight (Mn) in the range 200-500,000. The catalyst system includes a metallocene of the formula: [RmCpH(5-m)][RnCpH(5-n)]M(Z)Y wherein CpH is a cyclopentadienyl ligand, each R represents an alkyl or an aryl substituent on the CpH ligand or two R's may be joined together to form a ring, or the Rs in each CpH group when taken together represents an Si or C bridging group linking two CpH groups wherein the Si or C group may itself be substituted by hydrogen atoms or C1-C3 alkyl groups, M is a metal selected from hafnium, zirconium and titanium, Z is selected from a hydrogen atom, a trifluoromethane sulphonate, an alkyl and an aryl group, Y is selected from a, 1,3-diketonate and a &bgr;-ketoester arion, and each of m and n is same or different and has a value from 0 to 5.
