(57) [Summary] (Modified) [Structure] At least one selected from (A) a transition metal compound, (B) an organoaluminum oxy compound supported on a carrier, and (C) an alkyllithium or a dialkylmagnesium or a dialkylzinc. An olefin polymerization catalyst comprising two organometallic compounds, and a method for producing a polyolefin, which comprises polymerizing or copolymerizing an olefin in the presence of the catalyst. [Effect] The polymer can be stably produced with high polymerization activity without adhesion of the polymer to the wall of the polymerization vessel. |
