| titleOfInvention | Method for producing polyaryl ether |
| abstract | (57) [Summary] [Object] To provide a method for producing a polyaryl ether having no or reduced coloration. [Structure] An organic polar solution in which a dihalogenodiphenyl compound and a dihydric phenol compound are dissolved in an organic polar solvent is prepared, and then, when polycondensation is performed in the presence of an alkali metal compound in an inert gas atmosphere, a specific dihydric phenol is added. A method for producing a polyaryl ether, which comprises using 1% by weight or more of the total dihydric phenol and making the dissolved oxygen concentration in an organic polar solution 4 ppm or less. |
