摘要

Abstract

A pyridine-based diacid was synthesized

via

nucleophilic substitution reaction of 4-hydroxy benzoic acid with 2

6- dichloropyridine in the presence of potassium carbonate. The diacid was characterized using FT-IR and

H-NMR spectroscopic methods and also with elemental analysis. Polycondensation reaction of the diacid with different diols including 1

4-dihydroxy benzene

5-dihydroxy naphthalene

bis-phenol A and bis-phenol-P resulted in preparation of pyridine-based poly(ether-ester)s. The polymers were characterized and their physical and thermal properties including inherent viscosity

molecular weight

solubility

thermal stability

thermal behavior and crystallinity were studied. They revealed high heat-resistance and improved solubility in polar solvents. Structure-property relations for the prepared polyester were also studied.
