| titleOfInvention | Process for producing olefinic polymer |
| abstract | The process for producing an olefinic polymer comprises introducing a saturated aliphatic hydrocarbon in a liquid phase state and in a vapor phase state into the aforementioned fluidized-bed and (co)polymerizing in the condition that when the inside radius of the cylinder section of the fluidized-bed reactor is defined as a distance of 1, the relationship between the concentration (C 1 ) of the saturated aliphatic hydrocarbon put in a liquid state in the peripheral portion of the cylinder section at a relative distance of 0.7 to 1.0 from the center of the cylinder section as a start point and the concentration (C 2 ) of the saturated aliphatic hydrocarbon put in a liquid state in the center portion of the cylinder section at a relative distance less than 0.7 from the center fulfills the following equation: C 1 >C 2 at a place close to the upstream section of said gas distributing plate. |
