Abstract: Crystal structure of a novel aryl ether ketone polymer poly(aryl ether ketone ether ketone ketone containing meta-phenyl linkage)(PEKEKm K)} was determined by means of WAXDand ED.An orthorhombic unit cell is proposed containing two chains with a= 0.772 nm, b =0.604 nm and c =2.572 nm.According to the orthorhombic system, the10 reflections of this polymer were indexed

Key words: Poly(aryl ether ketone), Crystal structure, Wide-angle X-ray diffraction
