英文摘要: Abstract(#br)Norbornene polymerization was conducted with 2-(2,6-diisopropylanilino)-1,4-naphthoquinone-ligated nickel complex ( 1 ) activated by B(C 6 F 5 ) 3 and dried modified methylaluminoxane (dMMAO) in toluene at 40 °C. The 1 -B(C 6 F 5 ) 3 system showed higher activity than the 1 -dMMAO system and gave higher molecular-weight polynorbornene via coordination-insertion polymerization. The solubility of the polymer obtained by 1 -B(C 6 F 5 ) 3 was also higher than that obtained by 1 -dMMAO, and dissolved in cyclohexane even at room temperature. The self-standing films of the polynorbornene obtained by the B(C 6 F 5 ) 3 system were prepared by the solution casting method with cyclohexane. The films thus prepared showed good transparency in the UV–visible region. The 13 C NMR spectra of...
