| In this paper，the novel sp3C1-bridged constrained geometry complexes (CGC) for ethylene copolymerization with 1-octene were synthesized by fulvene was used as initial stuff and then reacting with lithium amine and MCl4 sequentially. All these complexes were well characterized by 1H-NMR，13C NMR，MS and EA. When activated with The CGC/methylaluminoxane (MAO) catalytic system show indicate high activation for copolymerization of ethylene and 1-octene under 1.0 atmospheric pressure. Among them, Complex 2/MAO shows higher activation 1.196 × 106 g-Polymer /mol-Zr•h (Pethylene = 1.0 atm，Al/Zr = 1000， time = 30 min) and the 1-Octene content in polymer = 5.46 mol%). Compared with classical CGC, this article offer a novel method for preparation of sp3C-bridged CGC with many advantages such as lower cost stuff，simple synthesis process and high catalytic activation. |
