Abstract

Poly(amide-ester)s containing p-aminobenzoic acid derived from three different diols (1,6-hexanediol, 1,4-butanediol, and trans-1,4-cyclohexanedimethanol) and two different acid chlorides (sebacoyl and adipoyl chloride) were synthesized by melt polymerization. The thermal and viscoelastic behaviour has been investigated and related to the chemical composition. All of the polymers synthesized showed an inherent viscosity ranging from 0·26 to 0·47 dl g-1. The Poly(amide-ester)s prepared by melt polymerization showed a lower molecular weight and melting temperature than polymers prepared by solution polymerization. The lower melting points of the polymers prepared by melt polymerization were due either to the lower molecular weight or to breakage of intermolecular hydrogen bonding, which was attributed to amide-ester exchange reactions during polymerization.
