Method for producing polyaryl ether |
| abstract |
(57) [Summary] [Object] To provide a method for producing a polyaryl ether having an improved coloring degree. [Structure] A dihalogenodiphenyl compound and a dihydric phenol compound are heated and stirred in an organic polar solvent in the presence of an alkali metal compound heat-treated in an inert gas. [Effect] A polyaryl ether having an improved coloring degree and excellent heat resistance and mechanical strength can be obtained. |
