Supported chemical compounds of formula (I) are new. Ac<+> = a cation; c = 1-10; b ≥ 0; T = a support; y ≥ 1; a = 0-10; a <.>y = c <.> b; N = a unit of formula (II); R = substituents, e.g. halogen or groups containing 1-40 carbon (C) atoms; X = 1-40 C groups; M = group IIa, IIIa, IVa and/or Va element(s); d, e, f = 0 or 1; g, h, k, r = 0-10; i = 0-1000; j = 1-6; S = spacers forming a covalent bond between M and T; w, z = 0, 1 or 2. Also claimed are (a) catalyst system containing (I); (b) the preparation of a polyolefin by polymerising olefin(s) in the presence of this catalyst system; and (c) polyolefins prepared in this way.
