中文摘要 | a series of nickel(ii) complexes bearing two nonsymmetric bidentate beta-ketoiminato chelate ligands have been prepared, and the structures of complexes [(2,6-me2c6h3)nc(ch3)c(h)c(ph)o](2)ni (4a) and [(2,6-me2c6h3)nc(ch3)c(h)c(cf3)o](2)ni (4c) have been confirmed by x-ray crystallographic analysis. these nickel(ii) complexes were investigated as catalysts for the vinylic polymerization of norbornene. using modified methylaluminoxane (mmao) as a cocatalyst, these complexes display very high activities and produce high molecular weight polymers. catalytic activity of up to 1.16 x 10(4) kg/mol(ni) .h and the viscosity-average molecular 9 weight of polymer of up to 870 kg/mol were observed. catalyst activity, polymer yield, and polymer molecular weight could be controlled over a wide range by the variation of the reaction parameters such as al/ni molar ratio, norbornene/catalyst molar ratio, monomer concentration, polymerization reaction temperature and time. |
