| 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 difference (ΔT) between the indicated values of the long and short thermometers inserted in the reactor shows a sharp decrease. And (II) the amount A (mol) obtained from the following equation (1) After supplying the organoaluminum compound of (III), the reaction is started while (III) further supplying a 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)) |
