Показано влияние увеличения продолжительности процесса аминолиза и количества ПЭТ на комплекс технологических свойств полиэфирамидов. По результатам испытаний установлено, что разработанные полиэфирамиды могут применяться в качестве отвердителей эпоксидных олигомеров.</p></abstract><trans-abstract xml:lang="en"><p>A method for the obtaining of polyesteramides based on recycled polyethylene terephthalate (PET) is presented. The process of aminolysis is studied by FTIR spectroscopy. The eff ect of increasing the duration of the aminolysis process and the amount of PET on the complex of technological properties of polyesteramides is shown. According to the test results, the developed polyesteramides can be used as hardeners for epoxy oligomers.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиэфирамид</kwd><kwd>вторичный ПЭТ</kwd><kwd>переработка</kwd><kwd>аминолиз</kwd><kwd>ИК-Фурьеспектроскопия</kwd><kwd>свойства материалов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polyethyramide</kwd><kwd>secondary PET</kwd><kwd>recycling</kwd><kwd>aminolysis</kwd><kwd>IR-Fourier spectroscopy</kwd><kwd>properties of materials</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Беданокова, А.Ю.
