| Research Abstract |
Development of aromatic polyesters from ferulic and caffeic acids, both of which can be obtained from agricultural wastes such as rice bran and extracted coffee beans, was performed. Poly(caffeic acid) showed glass transition at about 110 °C but was not thermally degraded below 320 °C. While copolyester of ferulic acid and glycolic acid spontaneously showed thermotropic liquid crystalline phase, poly(caffeic acid) formed liquid crystalline phase under shear above the glass transition temperatures.
