| 中文摘要 | a series of novel neutral nickel complexes 4a-e bearing modified beta-ketoiminato ligands [(2,6-(pr2c6h3)-pr-i)n=c(r-1)chc(2 '-r2c6h4)o]ni(ph)(pph3) (4a, r-1 r-2 = h; 4b, r-1 = h, r-2 = ph; 4c, r-1 = h, r-2 = naphth; 4d, r-1 = ch3, r-2 = ph; 4e, r-1 = cf3, r-2 ph) have been synthesized and characterized. molecular structures of 4b and 4e were further confirmed by x-ray crystallographic analysis. activated with b(c6f5)(3), all the complexes are active for the polymerization of ethylene to branched polyethylenes. ligand structure, i.e., substituents r-1 and r-2, greatly influences not only catalytic activity but also the molecular weight and branch content of the polyethylene produced. the phenyl-substituted complex 4b exhibits the highest activity of lip to 145 kg pe/mol(ni)center dot h center dot atm under optimized conditions, which is about 10 times more than unsubstituted complex 4a (14.0 kg pe/mol(ni center dot)h center dot atm). highly branched polyethylene with 103 branches per 1000 carbon atoms has been prepared using catalyst 4e. |
