Abstract
The present invention provides: an ethylene oligomerization method in which an ethylene oligomer is produced by reacting a chromium complex, an organic aluminium compound, and an organic zinc compound with ethylene; and the ethylene oligomer thereof.
Claims18
A method for oligomerization of ethylene, comprising a step of producing an ethylene oligomer by reacting ethylene with a catalyst, which contains a transition metal compound and a heteroatom ligand represented by the formula (R)nPNP(R)m (wherein R's are the same as or different from each other and are each independently selected from among any homo- and hetero-hydrocarbyl groups, and n and m are integers greater than 1), a cocatalyst, and a chain transfer agent in the presence of an organic compound.
