| titleOfInvention | Method for producing olefin polymer |
| abstract | (57) [Summary] (Modifications) [PROBLEMS] In an olefin polymerization using a metallocene-supported catalyst, together with a purified olefin polymer, Z A method for producing an olefin polymer, wherein a recyclable recovery solvent is obtained as a reaction solvent for olefin polymerization using a -N catalyst. SOLUTION: After polymerization of olefin in the presence of an olefin polymerization catalyst system containing a metallocene-supported catalyst and an organoaluminum compound, an alcohol having 1 to 4 carbon atoms is added to terminate the polymerization reaction, The slurry in which the coalesced mixture is dispersed in an aliphatic and / or alicyclic hydrocarbon solvent is subjected to an alkali treatment, and then the slurry is washed with water under a condition that the pH of the aqueous phase is maintained at an alkalinity of 11 or more. A method for producing an olefin polymer, comprising a polymer recovery step of washing a slurry containing a polymer with water under a condition that the pH of an aqueous phase is in the range of 7 to 9, separating an aqueous layer, and separating and drying the olefin polymer. |
