SUPPORTED TRANSITION METAL BIS (PHENOLATE) COMPLEXES AND THEIR USE AS CATALYSTS FOR OLEFIN POLYMERIZATION

摘要

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, R^1', R^2', R^3', R^4', A¹, A^1', are as defined herein, where A¹QA^1' are part of a heterocyclic Lewis base containing 4 to 40 non-hydrogen atoms that links A² to A^2' via a 3-atom bridge with Q being the central atom of the 3 -atom bridge.
