Abstract

One series of poly(ester‐anhydride)s, PEAs, was prepared by polycondensation of isophthaloyl chloride with mixtures of silylated 4‐hydroxybenzoic acid and various dihydroxy‐substituted naphthalenes. Most of these PEAs are semicrystalline materials with glass transition temperatures (T~g~) in the range of 130−190°C and melting temperatures (T~m~) in the range of 220−350°C. In a second series of PEAs, phenylhydroquinone, bisphenol‐A and 3,3′‐dimethylbisphenol‐A were used as diphenols. All but one PEA of the second series are amorphous materials with good solubility in chloroform and other organic solvents. GPC measurements indicated viscosity‐average molecular weights (M̄~v~) up to 38 000.

## SYNOPSIS A series of novel bis(phen0xy)naphthalene-containing polyamides having inherent viscosity up to 2.02 dL/g were synthesized by the direct polycondensation of the diamine 1,7bis(4-aminophenoxy)naphthalene with various aromatic dicarboxylic acids in N-methyl-8-pyrrolidone (NMP) using trip
