In a method for producing an olefin polymer to polymerize olefin by supplying olefin and a catalyst for polymerizing olefin into a vapor-phase fluidized bed reactor, the method includes introducing a fluidity improving agent comprising a compound represented by the following formula into the vapor-phase fluidized bed reactor. [R-O-(AO)m-COO-]nY (wherein, R represents an alkyl group, an alkenyl group or an aryl group, AO represents an alkylene oxide group, m represents the average addition molar number of alkylene oxide, Y represents a hydrogen atom, an alkali metal atom, an alkaline earth metal atom or an ammonium group, and n represents the valence of Y.) |
