Title:
CYCLIC POLY(ARYLENE ETHER KETONE) COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2020/189464
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a cyclic poly(arylene ether ketone) composition having high fluidity when heated and melted. The cyclic poly(arylene ether ketone) composition according to the present invention contains at least cyclic poly(arylene ether ketone) represented by formula (I), wherein the cyclic poly(arylene ether ketone) composition contains: 80 mass% or more of a cyclic component having 2-20 repeating units n in formula (I) with respect to the total amount of the cyclic poly(arylene ether ketone) represented by formula (I); and 30 mass% or less of a cyclic dimer component including two repeating units n with respect to the total amount of the cyclic poly(arylene ether ketone) represented by formula (I).
