Provided is a composition containing 60 wt% or more of cyclic polyphenylene ether ether ketone represented by formula (I). The cyclic polyphenylene ether ether ketone is a mixture of cyclic polyphenylene ether ether ketones having a different repeating number (m). The melting point of the composition is 270ºC or less. Also provided is a method for producing polyphenylene ether ether ketone by heating and polymerizing the cyclic polyphenylene ether ether ketone composition. (In the formula, m is an integer of 2 to 40.) |
