✦ Synopsis


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 dihsivity is related to the morphological structure in the dry state and the change induced by absorbed water.

## Abstract Our previous work showed that drawing polyamide 66 (PA 66) fibers at room temperature does not change the degree of crystallinity, but only increases the molecular orientation. We therefore have used a series PA 66 fibers with different draw ratios to establish a direct correlation betw
