Abstract: The variation of crystallinity of PEEKK samples treated at various temperatures has been studied by using wide-angle X-ray diffraction (WAXD). Based on X-ray scattering intensity theory and by using the graphic multipeak resolution method,the formula of crystallinity (Wc,x) for PEEKK is derived.The results calculated are compatible with the density and calorimetry measurements.

Key words: poly(ether ether ketone ketone), WAXD, crystallinity
