Metal complexes, catalyst compositions containing the metal complexes, and processes for making the metal complexes and the catalyst compositions are described for the manufacture of polymers from ethylenically unsaturated addition polymerizable monomers. The metal complexes have chemical structures corresponding to one of the following formulae: (Ia) (Ib) (VII) wherein M I and M II are metals; T is nitrogen or phosphorus; P is a carbon, nitrogen or phosphorus atom; groups R 1 , R 2 and R 3 may be linked to each other; Y is a divalent bridging group; X, X 1 , and X 2 are anionic ligand groups with certain exceptions; D is a neutral Lewis base ligand; and s, o, k, i, ii, p, m, a, b, c, d, e, t, and y are numbers as further described in the claims. |
