Zusammenfassung:	PURPOSE:To obtain a resin composition useful for instruments, electronic parts, parts of automobile, etc., having a high crystallization rate, containing high- melting polyetheretherketone. CONSTITUTION:This composition contains (A) high-melting polyetheretherketone having >=390 deg.C melting point and a repeating unit of the formula. The content of the component A is preferably 0.1-10wt.% based on the composition. The component A, for example, is obtained by heat-treating polyetheretherketone resin powder in a nitrogen atmosphere under about 150 atomic pressure at a temperature about 10 deg.C lower than the melting point of the polyetheretherketone resin under the pressure for about one day.
