| 英文摘要 | phosphino-phenolate neutral nickel catalysts 1-3/b(c6f5)(3), without the help of any organoaluminum compound, were found to be efficient catalytic systems for norbornene polymerization and its copolymerization with norbornene derivatives. the amount of b(c6f5)(3) required for achieving a high efficiency (3 equiv.) was markedly lower compared to previous reports, and high molecular weight polymers were obtained (>10(6) g mol(-1)). efficient incorporation of polar monomers nbc, nba, and nbm was also achieved in a controllable fashion, yielding high molecular weight copolymers. catalysts 1-3 were highly active for ethylene polymerization as single component catalysts, with an activity of up to 10(7) g mol(ni)(-1) h(-1), and catalyst 3 was more readily initiated at lower temperature. catalysts 1-3 were also efficient in incorporating norbornene (up to 30%) into the polyethylene backbone. bisligated phosphino-phenolate nickel complex 4 and salicylaldimine complex 5 were also studied for comparison, which further verified the unique performance of catalysts 1-3. preliminary nmr analyses were conducted to explore the norbornene polymerization mechanism. |
