英文摘要	A series of titanium complexes [(ar)nc(cf3)chc(r)o](2)ticl2 (4b: ar = -c6h4ome(p), r = ph; 4c: ar = -c6h4me(p), r = ph; 4d: ar = -c(6)h(4m)e(o), r = ph; 4e: ar = alpha-naphthyl, r = ph; 4f: ar = -c6h5, r = t-bu; 4g: ar = -c6h4ome(p); r = t-bu; 4h: ar = -c6h4me(p); r = t-bu; 4i: ar = -c6h4me(o); r = t-bu) has been synthesized and characterized. x-ray crystal structures reveal that complexes 4b, 4c and 4h adopt distorted octahedral geometry around the titanium center. with modified methylatuminoxane (mmao) as a cocatalyst, complexes 4b-c and 4f-i are active catalysts for ethylene polymerization and ethylene/norbornene copolymerization, and produce high molecular weight polyethylenes and ethylene/norbornene alternating copolymers. in addition, the complex 4c/mmao catalyst system exhibits the characteristics of a quasi-living copolymerization of ethylene and norbornene with narrow molecular weight distribution.
