| titleOfInvention | Seed powder, method for polymerizing olefins, and method for producing olefin polymer |
| abstract | An object of the present invention is to provide a method for efficiently producing an olefin polymer, a method for efficiently polymerizing olefins, and a material therefor, which suppress sheeting in a gas phase fluidized bed polymerization. Kind Code: A1 A seed powder to be charged into a gas-phase fluidized-bed polymerization reactor, comprising (A) a polyalkylene oxide alkyl ether, (B) a polyalkylene oxide block, (C) a higher aliphatic amide, and (D) A seed powder having at least one compound selected from alkyldiethanolamine, (E) polyalkylene oxide, and (F) polyoxyalkylenealkylamine. An olefin polymerization method for initiating polymerization after charging the seed powder into a gas-phase fluidized-bed polymerization reactor, and starting polymerization after charging the seed powder into a gas-phase fluidized-bed polymerization reactor And a method for producing an olefin polymer for polymerizing olefins.
