Method for recovering polyphenylene ether ether ketone and cyclic polyphenylene ether ether ketone composition |
| abstract |
【Task】 It is an object of the present invention to provide a method for recovering a highly pure cyclic polyphenylene ether ether ketone composition by a simple method. [Solution] A method of recovering a cyclic polyphenylene ether ether ketone composition from a mixture containing at least polyphenylene ether ether ketone, cyclic polyphenylene ether ether ketone and an organic polar solvent, the step of distilling off the organic polar solvent, and polyphenylene ether ether ketone A method for recovering a cyclic polyphenylene ether ether ketone composition, wherein a high-purity cyclic polyphenylene ether ether ketone composition is obtained only by performing a solid-liquid separation process in a temperature range in which water is insoluble. [Selection figure] None |
