中文摘要	the facile and efficient functionalization of polynorbornene has been achieved through direct copolymerization of norbornene (nb) with 5-norbornene-2-yl acetate (nba) or 5-norbornene-2-methanol (nbm) using a series of beta-ketiminato ni(ii)-me pyridine complexes 14 (scheme 2) in the presence of b(c6f5)3. remarkably, the monomer conversion could reach up to about 96% in 10 min in the nb/nba copolymerization. the copolymers with wide nba contents (3.338.4 mol %) were obtained by variation of reaction conditions. these copolymers have high molecular weights (mws) (mn = 41.8144 kg/mol) and narrow mw distributions (mw/mn = 1.802.27). in the absence of alkyl aluminum compounds, a monomer conversion of 81% was observed in the nb/nbm copolymerization, and copolymers with nbm content in the range of 11.221.8 mol % were obtained by variation of reaction conditions. in addition, ni(ii)-me pyridine complexes 2 was very active at a low b/ni molar ratio of 6, while bis-ligand complex 6 bearing the same ligand just showed moderate efficiency at a high b/ni molar ratio of 20.
