A mechanistic study of polyimide formation from diester-diacidsPrevious work has noted the presence of anhydride during the imidization step of polyimide polymer processing from diester-diacids and diamines. Comparison of the relative rates of reactions among model compounds demonstrates the intermediacy of anhydride in the imidization reaction. IR and NMR observations of mixtures of monomers confirm the production of anhydride as a necessary intermediate in the imidization reaction.
