The crystal structure of poly (ether ketone ketone)(PEKK) is predicted by using Cerius2 software according to the wide angle X-ray diffraction (WAXD) experiment result. The predicted structure has a planar zigzag chain conformation between ether oxygen and ketone carbons in an orthorhombic lattice. Average zigzag angle is 126° and average torsion angle is 30.32°, The WAXD powder pattern calculated from the crystal packing model is in good agreement with the experiment result.
