Abstract:
A method for making thermosetting polyimides from resveratrol including converting resveratrol to trisaniline, reacting trisaniline with one or more dianhydride and thermosetting endcap to form amic acid, thermally imidizing amic acid to form polyimide oligomer, and cross-linking polyimide oligomer with heat and pressure to generate polyimide thermoset.
