Beschreibung
Zusammenfassung:	This invention relates to supported catalyst compositions of transition metal complexes of a dianionic, tridentate ligand that features a central neutral heterocyclic Lewis base and two phenolate donors, where the tridentate ligand coordinates to the metal center to form two eight- membered rings. Preferably the bis(phenolate) complexes are represented by Formula (I): where M, L, X, m, n, E, E',Q, R1, R2, R3, R4, R1', R2', R3', R4', A1, A1', are as defined herein, where A1QA1' are part of a heterocyclic Lewis base containing 4 to 40 non-hydrogen atoms that links A2 to A2' via a 3-atom bridge with Q being the central atom of the 3 -atom bridge.
