. Anion exchange fiber materials were obtained by modification of polyacrylonitrile fiber “Nitron” from hydroxylamine. It was shown by potentiometric titration and using of IR spectroscopy that obtained polymers have an amidoxym- and hydroxamic groups in composition. Influence of different parameters on the modification process was investigated and conditions of obtain of ionites with high exchanging volume and chemostability were determined. For impart of chemostability to fibers their modification was carried out in the presence of cross - linking agent - hydrazine. It was determined that reaction kinetics was described by parameters typical to heterophase processes and the investigated reaction has a first order by hydroxylamine concentrations
