Abstract

The present invention relates to a method for ethylene oligomerization. According to the method of the present invention, highly active ethylene oligomerization reaction is possible by using a catalyst system including a novel chromium compound exhibiting high activity for ethylene oligomerization reaction, and therefore, polyethylene can be prepared using a small amount of comonomers or using only ethylene without comonomers.
