Summary New aromatic AB-type poly(etherimide)s containing various naphthylene links were prepared by the self-condensation of [2-(3,4-dicarboxyphenyloxy)-3, 6 and 7-naphthyl]oxyanilines hydrochlorides and 5-(3,4-dicarboxyphenyl)oxy-1-naphthylamine hydrochloride. The polymerization performed in NMP/pyridine or DMAc/Et3N in the presence of triphenylphosphite(TPP) activator was found to proceed to imide bond formation. Inherent viscosities of the polymers were in the 0.39-0.94dL/g range. Properties of the poly(etherimide)s were investigated and discussed in terms of chain rigidity resulting from different naphthylene links. All the poly(etherimide)s were highly thermostable up to 600°C with 10% weight loss and showed chemical resistance against chloroform even at higher temperatures.
