摘要
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.
