| 英文摘要 | A new titanium complex [PhN=C(Ph)CHC(CF3)O](2)TiCl2 (2a), with an asymmetric beta-enaminoketonato [N,O] ligand, has been synthesized and fully characterized. With modified methylaluminoxane as a cocatalyst, the behaviors of ethylene polymerization, and ethylene/alpha-olefin and ethylene/norbornene copolymerization have been explored in detail. Relative to its regioisomer 2b ([PhN=C(CF3)CHC(Ph)O](2)TiCl2), the present catalyst exhibits signifi cant predominance. The catalytic activity in 2a-catalyzed homo- and copolymerization are much higher than those in 2b-catalyzed (co)polymerization. Furthermore, compared with 2b, catalyst 2a possesses an obviously stronger ability towards copolymerization, due to a wide coordination space caused by exchanging the position of the phenyl group and trifluoromethyl group on the framework. |
