| titleOfInvention | Olefin Polymerization Method |
| abstract | (57) [Summary] (Revised) [Purpose] The production of olefin polymer stably and continuously over a long period of time, and the heat of polymerization can be efficiently removed. Phase polymerization method. [I] A main polymerization step of gas phase polymerization or copolymerization of an olefin with a solid catalyst component in the presence of a low boiling point non-polymerizable hydrocarbon in a reaction system kept in a fluid state, and [II] A first circulation step of circulating a part of the low-boiling point non-polymerizable hydrocarbons discharged from the upper part of the gas-phase polymerization device from the lower part of the gas-phase polymerization device; Olefin supplied to the above-mentioned [II] and / or [III] circulation step, including a second circulation step of liquefying a part of the non-polymerizable hydrocarbon and circulating it to the reaction system in the gas-phase polymerizer. In the gas phase polymerization of [III], in the second circulation step, the liquefied low-boiling point non-polymerizable hydrocarbon is contacted in liquid form with the powder particles scattered upward from the powder surface of the fluidized bed. It is characterized by circulating in the vicinity. |
