| 中文摘要 | three heteroligated (salicylaldiminato)(beta-enaminoketonato)titanium complexes [3-bu-t-2-oc6h3ch=n(c6f5)][(p-xc6h4)n=c(bu-t)chc(cf3)o]ticl2 (3a: x = f, 3b: x = cl, 3c: x = br) were synthesized and investigated as the catalysts for ethylene polymerization and ethylene/norbornene copolymerization. in the presence of modified methylaluminoxane as a cocatalyst, these unsymmetric catalysts exhibited high activities toward ethylene polymerization, similar to their parallel parent catalysts. furthermore, they also displayed favorable ability to efficiently incorporate norbornene into the polymer chains and produce high molecular weight copolymers under the mild conditions, though the copolymerization of ethylene with norbornene leads to relatively lower activities. the sterically open structure of the beta-enaminoketonato ligand is responsible for the high norbornene incorporation. the norbornene concentration in the polymerization medium had a profound influence on the molecular weight distribution of the resulting copolymer. |
