摘要： Heterocyclic amido transition metal complexes are disclosed for use in alkene polymerization to produce polyolefins, preferably multimodal polyolefins. The heterocyclic amido transition metal complexes are formed by the chelation of a tridentate dianionic heterocyclic amido ligand to a group 3, 4, or 5 transition metal, where the tridentate ligand coordinates to the metal forming a five-membered ring and an eight-membered ring.

摘要： This invention relates to a homogeneous process to produce propylene polymers using 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′,
and
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.-
