(57) [Abstract] [Purpose] When a polyolefin composed of a solid catalyst component containing titanium and / or vanadium and an organoaluminum compound is used to produce a polyolefin in a gas phase, Provided is a method for easily preventing the generation of a molten resin due to the generation of static electricity without providing new equipment. [Structure] Particles which have been treated with at least one treatment agent selected from the group consisting of carbon monoxide, carbon dioxide, alcohols, ketones, nitrogen oxides and aldehydes and which can form a fluidized bed are prepared in advance. Fill the reactor and start the reaction. |
