Novel Diols containing ester and amide groups and resulting poly(ester amide ester)s
The reaction of terephthaloyl chloride and 4-hydroxybenzoic acid resulted in terephthalyl bis(4-oxybenzoic) acid. This diester diacid was converted into its corresponding diester diacid chloride (terephthaloyl dioxydibenzoylchloride) via a reaction with thionyl chloride. Diols with preformed ester and amide groups were prepared through the reaction of terephthaloyl dioxydibenzoylchloride with 4-aminophenol and 5-amino-1-naphthol. Polycondensation reactions of the prepared diols with different aromatic and aliphatic diacid chlorides afforded eight aromatic and semiaromatic poly(ester amide ester)s. The polymers were fully characterized, and their physical and thermal properties were studied. (C) 2004 Wiley Periodicals, Inc.
