Beschreibung
Zusammenfassung:	To provide a method for treating polyphenylene ether which can enhance solvent solubility of polyphenylene ether.SOLUTION: A method for producing polyphenylene ether includes a heating step of heating and melting raw material polyphenylene ether to a melting temperature or higher, and a cooling step of cooling the raw material polyphenylene ether in a molten state, wherein the cooling step is a step of cooling the raw material polyphenylene ether while keeping average cooling speed of 10°C/min or more, in at least a temperature range from the melting temperature to lower than a glass transition temperature.SELECTED DRAWING: None 【課題】ポリフェニレンエーテルの溶媒溶解性を高めることが可能なポリフェニレンエーテルの処理方法を提供する。【解決手段】本発明のある形態は、原料ポリフェニレンエーテルを溶融温度以上に加熱して溶融させる加熱工程と、溶融状態にある前記原料ポリフェニレンエーテルを冷却させる冷却工程とを含み、前記冷却工程が、少なくとも前記溶融温度からガラス転移温度未満までの温度範囲において、１０℃／ｍｉｎ以上の平均冷却速度を維持して前記原料ポリフェニレンエーテルを冷却する工程であることを特徴とする、ポリフェニレンエーテルの製造方法である。【選択図】なし
