| 英文摘要 | In this contribution, the influence of substitutions ranging from electron donating to the electron withdrawing, on the bis(arylimino)acenaphthenes-palladium catalysts is investigated. A series of symmetrical bis(arylimino) acenaphthene-palladium complexes, [1,2-bis[2,6-(CHPh2)(2)-4-R-C6H2N]C2C10H6]PdMeCI (R = Me L1, Et L2, Pr-t L3, Bu-t L4, Cl L5, F L6) has been prepared and investigated toward the polymerization of nobornene as well as its copolymerization with ethylene comonomer. These palladium complexes displayed moderate to high activities for norbomene polymerization in the presence of MAO and (C6F5)(4)B center dot C6H5NH(CH3)(2) co-catalysts. Specifically, complex Pd4 (R = Bu-t) displayed a highest activity up to 6.1 x 10(6) g(PNBE) mol(pd)(-1) h(-1) with 54.2% conversion of monomer at 60 degrees C and showed exceptionally high thermal stability (act: 4.81 x 10(5) g(PNBE) mol(pd)(-1) h(-1) with 51.2% conversion at 100 degrees C), and generating insoluble polynorbomene. Toward the copolymerization of norbornene-ethylene, Pd4 exhibited good activities with high incorporation of ethylene (up to 49.1%) and the resultant copolymer showed high molecular weights as high as 100.3 kg/mol(-1) with narrow molecular weights distributions (PDI = 2.15). |
