  • Alkene polymerization using beta-ketoiminato metal complexes
    Publication number: 20090192278
    Abstract: Group (IV) and (X) metal complexes with ketoiminate ligands are prepared by deprotonation of a ketoimine ligand followed by reaction with the appropriate metal halide. In preferred cases, the compounds are titanium (IV), zirconium (IV) and hafnium (IV), preferred cases, the compounds are titanium (IV), zirconium (IV) and hafnium (IV) complexes with (arylimino-alkyl)-spiro[4,5]decan-6-one ligands. The compounds are useful as catalysts for polymerizing ethylene, C3-C10-alpha olefins and C4-C10 cyclic alkenes and for copolymerizing ethylene with comonomers.
