Abstract

In this study, a new series of thermally stable polyamides and copolyamides are prepared through reaction of oxazolopyridine functional diamine, 2-(3,5-diaminophenyl) oxazolo [4,5-b] pyridine with four commercial dicarboxylic acids: pyridine 2,6-dicarboxylic acid, pyridine 2,5-dicarboxylic acid, 4,4′-dicarboxylic acid diphenyl sulfone and 4,4′-dicarboxylic acid diphenyl ether. The synthesized polymers were characterized by FT-IR and 1HNMR spectroscopy. The physical properties of the polymers including solubility and viscosity were studied. The results displayed good solubility, viscosity and high thermal stability. Their viscosities and glass transition temperatures are in the range of 0.66–0.73 and 170–200 °C, respectively. Thermal stabilities for 10% weight loss temperature are higher than 445–500 °C.
