Abstract

A cyclic poly (phenylene ether ether ketone) composition includes not less than 60% by weight of a cyclic poly (phenylene ether ether ketone) represented by the following Formula (I), which is characterized in that the cyclic poly (phenylene ether ether ketone) is a mixture of cyclic poly (phenylene ether ether ketone)s having different repeating numbers (m) and the composition has a melting point of not higher than 270° C.; and a method of producing a poly (phenylene ether ether ketone) characterized by heat-polymerizing the cyclic poly (phenylene ether ether ketone) composition: where m represents an integer of 2 to 40.
