(57) Disclosed is a catalyst suitable for the polymerization of 1-olefins, the catalyst comprising an activated amount selected from (1) a nitrogen-containing iron compound having the formula Z and (2) an organoaluminum compound and a hydrocarbyl boron compound. Wherein X represents an atom or group covalently or ionically bonded to Fe, b is the valence of the atom or group X, and the catalyst is (3) a solid particulate support material. It is characterized by being performed. Embedded image |
