На их основе путем алкилирования получены хелатные иониты с аминоацетатными и аминодиацетатными функциональными группами. Определена механическая прочность моноволокон полученных ионитов. С использованием предложенного ранее метода анализа результатов потенциометрического титрования определены кислотно-основные свойства синтезированных материалов с разделением функциональных групп по видам.</p></abstract><trans-abstract xml:lang="en"><p>Fibrous amino carboxylic ion exchangers with different anionic and cationic exchange capacity have been prepared by a new method of the high-temperature catalytic amination of the PAN fiber nitrile groups. Chelating ion exchangers with aminodiacetic functional groups has been obtained from these ion exchangers by alkylation reaction. Mechanical properties of monofilaments of obtained materials have been studied. Acid-base properties for each functional group type of the synthesized ion exchangers have been determined by the earlier proposed method.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Druzhinina T.
