  • Catalyst complex and process for producing multimodal molecular weight polyolefins
    Patent number: 8420563
    Abstract: Multinuclear catalyst complex comprising two or more active metal centers and at least one phenoxyimine derivative and at least one substituted cyclopentadienyl, indenyl or fluorenyl derivative, each phenoxyimine derivative being bonded to a cyclopentadienyl, indenyl or fluorenyl derivative forming a ligand framework, the cyclopentadienyl, indenyl or fluorenyl derivative being coordinated with one of the metal centers and the phenoxyimine derivative being coordinated with an active metal center other than the metal center the cyclopentadienyl, indenyl or fluorenyl derivative is coordinated with, and wherein the phenoxyimine derivative is derived from a phenoxyimine compound of the formula wherein R1 is hydrogen, alkyl, cycloalkyl, aryl or aralkyl; R2 is hydrogen, halogen, alkyl, cycloalkyl, aryl, O-alkyl or aralkyl; and R3 is alkyl, cycloalkyl, aryl or aralkyl, process for preparing a multinuclear catalyst composition comprising the steps of bonding the substituted phenoxyimine compound to a substitute
