| Abstract: | The synthetic route to polyetherimides by displacement of nitro-groups from disubstituted bis-imides by the dianion of bisphenols are described. The prepration of bis-imides and bisphenol dianions, their polymerization, and some of the properties of the polymers are presented in detail. The 13C-NMR spectra of intermediates and products were used to establish compositions and determine molecular weights. |
