| 中文摘要 | using the wide-angle x-ray diffraction method, the variation of crystallographic parameters of poly(aryl ether ether ketone ketone) (peekk) has been studied in different heat treatment temperatures. all the reflections and their intensities as well as their miller indices are presented in detail according to an orthorhombic system. the investigation indicates that the unit cell parameters a, b, c and the unit cell volume v systematically decrease with increasing heat treatment temperature. this variation is interpreted by the change of conformation of polymer molecular chains during thermal treatment. the results calculated from the formula of degree of crystallinity (w-c,w-x) for peekk, which was derived based on x-ray scattering intensity theory and the graphic multipeak resolution method, are compatible with the density measurement (w-c,w-d) and calorimetry (w-c,w-h) values.
