    摘要: 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.)

    摘要: The gas-phase fluidized-bed reactor conducting reaction by feeding a gas, through a gas-distribution plate located at the lower part of a reaction vessel, into a fluidized bed formed on the gas-distribution plate, wherein the reaction vessel is made up so as to have a narrowed part at a specified position of the gas flow passage above the gas-distribution plate, and the fluidized bed is formed in the area from below the narrowed part to above the narrowed part. The gas-phase fluidized bed rector of the present invention allows manufacturing polymers having excellent homogeneity of polymer structure in gas-phase polymerization.
