Crystal structure of a novel aryl ether ketone polymer {poly(aryl} ether ketone ether ketone ketone containing meta phenyl {linkage)(PEKEK m K)} was determined by means of WAXD and 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, the 10 reflections of this polymer were indexed.
