Metal-containing polyimides having ionic linkages in the main chain, and their parent polyimides, were synthesized. The structures of these materials were investigated by using solid-state n.m.r, spectroscopy and some characteristic features of the 1 s C n.m.r, spectra of the polyimides are described.
