Abstract: | Reaction of 5‐amino‐1‐naphthol with pyromellitic dianhydride (PMDA), benzophenonetetracarboxylic dianhydride (BTDA), and hexafluoroisopropylidene diphthalic anhydride (6FDA) afforded aromatic diols with preformed imide structure. High temperature solution polycondensation reactions of the obtained diimide‐dinaphthols with aromatic and aliphatic diacid chlorides resulted in the preparation of nine different poly(ester‐imide)s. These were fully characterized, and the physical and thermal properties of the obtained polymer were studied. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 2567–2572, 2003 |
