Use of new diimide–dinaphthols in preparation of novel thermally stable poly(ester–imide)s

Abstract Reaction of 5‐amino‐1‐naphthol with pyromellitic dianhydride, benzophenonetetracarboxylic dianhydride, and hexafluoroisopropylidene diphthalic anhydride afforded aromatic diols with preformed imides structure. High temperature solution polycondensation reactions of the obtained diimide–dinaphthols with aromatic and aliphatic diacid chlorides resulted in preparation of nine different poly(ester–imide)s. They were fully characterized and the physical and thermal properties of the obtained polymer were studied. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 88: 2168–2172, 2003
