A series of sequenced sulphonated naphthalenic polyimides with improved solubility were prepared by polycondensation in m-cresol using aromatic diamines containing phenylether bonds and/or bulky groups. Sulphonated polyimides were characterized by nuclear magnetic resonance (NMR) and infrared (IR) s...
