A supported catalyst system contains sub-group III, IV, V and/or VI transition metal compound(s) (A) and cocatalyst(s) of formula (B), neither of which is covalently bound to the support. In (B), R<6> = halogen or a group containing 1-40 carbon (C) atoms, e.g. 1-40C (halo)alkyl, 6-40C (halo)aryl or 7-40C (halo)arylalkyl; X = a 1-40C group, e.g. a divalent 1-40C (halo)alkylene, 6-40C (halo)arylene, 7-40C (halo)arylalkylene, 2-40C (halo)alkynylene or 2-40C (halo)alkenylene, or a trivalent group, e.g. 1-40C (halo)alkan-tri-yl, 6-40C (halo)aren-tri-yl, 7-40C (halo)aren-alkan-tri-yl, 2-40C (halo)alkyn-tri-yl or 2-40C (halo)alken-tri-yl group; M<3> = group IIa, IIIa, IVa and/or Va element(s); a, b, c, g, h, p = 0-10; a = b.c; n, m, l = 0 or 1; i = 0-1000; j = 1-6; A = a cation of a group Ia, IIa or IIIa element, a carbenium, oxonium or sulphonium cation or a quaternary ammonium compound; if a = 0, (II) is a neutral chemical compound; and if a > 1, (II) is a negatively charged compound with b A(c<+>) cations as counter-ions. |
