摘要：
The object of the invention is to provide a method of economically and efficiently recovering an industrially useful cyclic poly(phenylene ether ether ketone) composition in a short time. A mixture including linear poly(phenylene ether ether ketone) and cyclic poly(phenylene ether ether ketone) is exposed to a ketone-based solvent and is then subjected to solid-liquid separation. This enables recovery of a cyclic poly(phenylene ether ether ketone) composition including a cyclic poly(phenylene ether ether ketone) mixture of cyclic poly(phenylene ether ether ketone)s having different repeating numbers m.
