| titleOfInvention | Gas phase polymerization method |
| abstract | (57) [Summary] [Problem] The probability of existence of powder is low in an upper part of a fluidized bed area, particularly in a range from a powder surface of a fluidized bed to a deceleration zone, and the effect of washing the side wall surface of the reactor with powder is also obtained. Despite being thin, polymer particles etc. having a terminal velocity smaller than the terminal velocity assumed by the reactor in the fluidized bed are suspended, and these are one of the destabilizing factors of the fluidized bed. Under the conditions for producing a polyolefin having a large [η], the destabilizing factor often becomes dominant, and a simple method capable of stably operating such a polymer has been desired. [Means] 1 mol of organic aluminum supplied to a fluidized bed A gas phase polymerization method for olefins, wherein 0.001 to 1 mol / mol of a catalyst deactivator is supplied from the upper part of the fluidized bed to the deceleration region. |
