Abstract Sulfonated aromatic polyamide and different salts were synthesized. Water vapor diffusion in these polymers and X‐ray diffraction of these polymers before and after water immersion were studied. The concentration dependence of the diffusivity is related to the morphological structure in the dry state and the change induced by absorbed water. © 1993 John Wiley & Sons, Inc.
