PROBLEM TO BE SOLVED: To provide a method for efficiently producing an ethylene polymer particularly suitable for large-size blow such as blow having an excellent balance between rigidity and creep resistance. SOLUTION: (1) Chromium carboxylate, chromium- A chromium compound having an organic group selected from 1,3-diketo compounds, chromate esters and chromamide compounds, an alumoxane, an organic metal alkoxide and / or an organic metal siloxide supported on a carrier, and (2) an organic lithium compound Organic magnesium compounds, A method for producing an ethylene-based polymer, comprising using an activator selected from an organic aluminum compound and an organic boron compound. |
