Abstract: 4,4'-bis(β-naphthoxy)diphenylsulfone(BNODPS) was synthesized by reaction of β-naphthol with bis(4-chlorophenyl) sulfone in DMSO in the presence of KOH. Five polyaryl ether sulfone ether ketone ketones containing naphthalene links were prepared by low temperature solution polycondensation of BNODPS with terephthaloyl chloride(TPC), isophthaloyl chloride(IPC) and 2,5-dichloroterephthaloyl chloride(DCC), respectively in 1,2-dichlorothane and in the presence of AlCl3 and N-methylpyrrolidone. The polymers as characterized by IR, XRD, DSC and TG techniques are non crystalline and have high glass transition temperature, good thermostability and solubitity.
