i.r. and ~3C-CP-MAS-NMR spectra were recorded for polyamidocarboxylic acid, polyimide and polyisoimide based on pyromellitic acid dianhydride (PMDA) and 4,4'-diaminodiphenylmethane (MDA), and of polyimide based on PMDA and 4,4'-diaminodiphenylether. The 13C-NMR spectra were interpreted and bands in
