Для валидации метода проведена серия экспериментов с отвердителями различного строения. Результаты подтверждают применимость метода для случаев, когда классические титриметрические или спектроскопические методы не обеспечивают точного определения аминного эквивалента. Кроме того, разработан пошаговый алгоритм анализа, упрощающий исследование таких трудных для характеристики отвердителей. Метод обеспечивает повышенную точность и расширяет перечень аминов, пригодных для стехиометрических расчетов в эпоксидных системах отверждения.</p></abstract><trans-abstract xml:lang="en"><p>A method for determining the amine hydrogen equivalent weight using differential scanning calorimetry has been developed. A series of differential scanning calorimetry experiments were conducted on amine hardeners of varying molecular architectures in case of method’s validation. The results demonstrate method’s applicability for hardeners which amine equivalent weight cannot be determined properly by traditional titration or spectroscopic methods. Additionally, a step-by-step analytical algorithm was established to streamline the characterization of such challenging hardeners. This method offers improved precision and expands the range of amines suitable for stoichiometric calculations in epoxy curing systems.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аминный эквивалент</kwd><kwd>эпоксидный эквивалент</kwd><kwd>аминные отвердители</kwd><kwd>эпоксидный олигомер</kwd><kwd>дифференциально сканирующая калориметрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>amine hydrogen equivalent weight</kwd><kwd>epoxy equivalent weight</kwd><kwd>amine hardeners</kwd><kwd>epoxy oligomer</kwd><kwd>differential scanning calorimetry</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">Мачульскайте Т.В., Спиридонова А.С., Дмитриева Ю.Н., Керестень А.А., Румянцев Д.А., Пирожников П.Б.
