METHOD FOR PRODUCING CYCLIC POLYPHENYLENE ETHER ETHER KETONE COMPOSITION AND LINEAR POLYPHENYLENE ETHER ETHER KETONE, AND METHOD FOR PRODUCING POLYPHENYLENE ETHER ETHER KETONE

摘要

There is provided a method of economically producing a cyclic poly(phenylene ether ether ketone) composition and a linear poly(phenylene ether ether ketone) with high efficiency in a short time. The production method of the cyclic poly(phenylene ether ether ketone) composition and the linear poly(phenylene ether ether ketone) uses (i) an organic polar solvent of not less than 1.20 liters and not more than 100 liters relative to 1.0 mol of a benzene ring component in a reaction mixture, and (ii) as a base, at least one species selected between sodium carbonate and sodium bicarbonate, or a base mixture of at least one species selected between sodium carbonate and sodium bicarbonate and at least one species selected among carbonates and bicarbonates of alkali metals having higher atomic numbers than sodium.
