Abstract: Three series of poly(aryl ether ketone)s(PAEKs) were synthesized from varied ratio of 1-chloro-4-(4-chlorobenzoyl)naphthalene and 4,4′-difluorobenzophenone with three different bisphenols respectively. The polymers have been studied by IR、DSC, mechanical property and solubility measurements. The results showed that the T_g of the polymers increased with the increase of 1,4-naphthylene and the tensile strength got a maximum at a certain naphthylene content. The PAEKs were soluble plastics with excellent heat
