Operation of olefin gas phase polymerization reactor |
| abstract |
(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 of preventing the formation of sheet polymer. [Structure] By supplying an organic acid to the gas circulation system of the reactor, it is possible to prevent the formation of a sheet polymer in the reactor. |
