  Mono, di and tetranuclear ansa zirconocene complexes as catalysts for the homogeneous and heterogeneous polymerization of ethylene

  摘要：

  Mono, di and tetranuclear ansa zirconocene complexes have been synthesized and characterized. After activation with methylalumoxane (MAO) these catalysts were used for the homogeneous and heterogeneous polymerization of ethylene. The properties of the catalysts and the produced polymers were compared. The multinuclear catalysts show a different performance than the corresponding mononuclear derivatives. The tetranuclear catalysts have the lowest activities because of steric crowding. (C) 2002 Elsevier Science B.V. All rights reserved.

  A series of 21 dissymmetric dinuclear ansa zirconocene complexes and their ligand precursors have been synthesized and characterized. After activation with methylalumoxane (MAO), these catalysts polymerize ethylene with different productivities and polydispersities in homogeneous and heterogeneous media. The tendencies of these series are shown. (C) 2002 Elsevier Science B.V. All rights reserved.
