摘要

A cyclic polyphenylene ether ether ketone composition and a linear polyphenylene ether ether ketone in an economical and short time efficient manner. A process for producing a cyclic polyphenylene ether ether ketone composition and a linear polyphenylene ether ether ketone, comprising the steps of: (i) mixing an organic solvent having a boiling point of 1.20 liters or more and 100 liters or less with respect to 1.0 mol of a benzene ring component in a reaction mixture; At least one member selected from sodium carbonate and sodium bicarbonate or at least one member selected from sodium carbonate and sodium bicarbonate and an alkali metal carbonate having an atomic number higher than that of sodium carbonate And mixed bases with at least one selected from salts and bicarbonates are used.
