| titleOfInvention | Gas phase polymerization of olefins |
| 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, (EN) Provided is an operation method which does not cause the formation of a sheet polymer at the initial stage of polymerization and other abnormalities. [Constitution] After filling the reactor with the seed polymer, (I) supplying the organoaluminum compound into the reactor until the center of the amplitude of the electrostatic current in the reactor becomes zero and the amplitude shows a minimum value. Then, (II) after supplying the amount A (mol) of the organoaluminum compound obtained from the following formula (1), (III) further starting the reaction while further supplying the catalyst. A = 0.044 × V 2/3 + aW (1) (V: total system volume (m 3 ), W: seed polymer weight (to n), a: coefficient of 0 to 89 (mol / ton)) |
