    摘要: Catalyst compositions comprising 1) one or more bimetallic Group 3-6 or Lanthanide metal complexes corresponding to the formula:  wherein: M and M′ are independently Group 3, 4, 5, 6, or Lanthanide metals; L is a divalent group (or trivalent group if bound to Q) having up to 50 nonhydrogen atoms and containing an aromatic &pgr;-system through which the group is bound to M, said L also being bound to Z; L′ is a monovalent group or a divalent group (if bound to L″ or Q), or a trivalent group (if bound to both L″ and Q) having up to 50 nonhydrogen atoms and containing an aromatic &pgr;-system through which the group is bound to M′; L″ is a monovalent group or a divalent group (if bound to L′ or Q), or a trivalent group (if bound to both L′ and Q) having up to 50 nonhydrogen atoms and containing an aromatic &pgr;-system through which the group is bound to M′, or L″ is a moiety comprising boron or a member of Group 14 of the Periodic Table of the Elements, and optionally also comprising nitrogen, phosphorus, sulfur or oxygen, said L″ having up to 20 non-hydrogen atoms; Z is a moiety comprising boron or a member of Group 14 of the Periodic Table of the Elements, and also comprising nitrogen, phosphorus, sulfur or oxygen, said Z having up to 20 non-hydrogen atoms; X, X′ and X″ are as defined in the specification; Q is a divalent anionic ligand group bound at one terminus to either Z or L and bound at the remaining terminus to either L′ or L″, said Q having up to 20 nonhydrogen atoms; and x, x′, and x″ are independently integers from 0 to 3; and 2) one or more activating cocatalysts; wherein activating cocatalyst component 2) causes both metal centers, M and M′, of the one or more bimetallic metal complexes 1) to be catalytically active for the polymerization of addition polymerizable monomers.
