Notes:
13Carbon chemical shifts are reported for polyimide and polyamic acid prepared from 3-aminophenylacetylene, 1,3-bis(3-aminophenoxy) benzene, and 3,3′,4,4′-benzophenoetetracarboxylic dicanhydride. The shielding parameters are correlated with the structure. A spectral analysis of model compounds, monomers, and other oligomers is also included. This analysis resulted in an analytical method by 13C-NMR spectroscopy of determining the amic acid-imide ratio in the partly cured polyamic acid. The development of the method is discussed.
