A diacid (TOBA) containing an ester group was synthesized by reaction of terephthaloyl chloride with 4‐hydroxybenzoic acid. Reaction of the obtained diacid with thionyl chloride resulted in preparation of the related diacid chloride (TOBC). Nucleophilic substitution reaction of 4‐aminophenol and also 5‐amino‐l‐naphthol with the prepared diacid chloride afforded two aromatic diols containing ester and amide groups, respectively. Aromatic and semi‐aromatic poly(ester‐amide‐urethane)s were prepared via addition polymerization of different diisocyanates with novel diols. The prepared polyurethanes showed improved thermal stability.
