Abstract:Ethylene Polymerization eatalyzed by Iron-Nickel Binuclear catalysts supported by different cocatalysts was investigated.The effects of Al/(Fe+Ni) molar ration on the Ethylene Polymerization were studied systemieally in this paper.
In Ethylene Polymerization, Iron catalytic active centers synthetic linear polyethylene,Nickel catalytic active centers synthetic branched polyethylene. In contrast, Binuclear Catalysts activities higher than both mononuclear Iron complex and mononuclear Nickel complex,and weight distribution of polyethylene catalysted by mononuclear is narrower.In the condition of high temperature, binuclear system is more stable than mononuclear system.
The effects of different cocatalysts was investigated.
