Method for producing polyphenylene ether |
| abstract |
(57) [Problem] To provide a method for efficiently producing polyphenylene ether at a high monomer concentration. SOLUTION: The phenolic compound concentration based on the whole charged mixture is set to 23% by weight or more, and the amount of the catalyst specific (copper compound, bromine compound) component is 5 mmol or less and the amount of bromine atom per 1 kg of the total charged mixture. To a specific amount of 20 mmol or less. |
