  名称：

  C2-bridged metallocene dichloride complexes of the types (C13H8–CH2CHR–C9H6−nR′n)ZrCl2 and (C13H8–CH2CHR–C13H8)MCl2 (n=0, 1; R=H, alkenyl; R′=alkenyl, benzyl; M=Zr, Hf) as self-immobilizing catalyst precursors for ethylene polymerization

  摘要：

  A total of 15 C-2-bridged fluorenylidene indenylidene and bis(fluorenylidene) metal dichloride complexes (metal = Zr, Hf) and the corresponding ligand precursors have been prepared and characterized. omega-Alkenyl substituents with various chain lengths in the C-2-bridge or in position 3 of the indenylidene moiety have an impact on the polymerization activity of the catalysts and the molecular weights of the produced polyethylenes. These omega-alkenyl substituents cause 'self-immobilization' due to their incorporation into the backbone of a growing polymer chain providing heterogeneous catalyst systems.
