摘　　要：Cyclodextrin was pretreated by methylaluminoxane (MAO) and subsequently reacted with 8 aminoquinoline nickel dichloride complex to yield the supported catalyst, which was characterized by ICP, IR and XPS methods. Using MAO as cocatalyst, the catalytic activity of this supported catalyst was investigated at various reaction temperature and Al/Ni molecular ratio. The results showed that, despite possessing a number of polar groups, the supported catalyst displayed relatively high activity over 1×10 5 g ethylene/(mol Ni·h) under mild conditions.Cyclodextrin was pretreated by methylaluminoxane (MAO) and subsequently reacted with 8 aminoquinoline nickel dichloride complex to yield the supported catalyst, which was characterized by ICP, IR and XPS methods.
