General description
Poly(pyromellitic dianhydride-co-4,4′-oxydianiline), amic acid solution (PAA) converts to polyimide at 300oC. The FTIR spectra indicates a carbonyl stretch of carboxylic acids in PAA at 1650 cm-1. Following the imidization process, the peak at 1720cm-1 grows, indicating the formation of imide group.
Application
It is used as a precursor for polyimide coatings.
It may also be used as a precursor for the preparation of carbon hollow fiber membranes.

The triblock copolymers with the majority phase comprising fluorinated polyimide and the minor phase consisting of poly (ε-caprolactone) (PCL) were synthesized through Diels-Alder reaction between PI-Maleimide and PCL-Furfuryl Amine. The chemical composition and structure of the copolymers were characterized by
