Основной причиной потери адгезии и разрушения таких покрытий является диффузия агрессивных жидкостей через полимерную матрицу. Несмотря на подробную изученность сорбции воды термореактивными полимерами, данные о термодинамической совместимости эпоксидно-фенольных материалов с органическими растворителями представлены недостаточно. В работе для количественной оценки совместимости использован критерий Флори-Хаггинса, позволяющий прогнозировать образование истинного раствора или гетерофазной дисперсии в системе полимер–жидкость. Объектами исследования служили свободные пленки толщиной 180 ± 25 мкм на основе эпоксидно-фенольной смолы, отвержденной тремя ароматическими полиаминами: на основе карданола, диэтилтолуолдиамином и метилен-бис(орто-этиланилином). Кинетику сорбции в дистиллированной воде и о-ксилоле изучали гравиметрическим методом, изменение термомеханических свойств оценивали методом дифференциальной сканирующей калориметрии (ДСК). Установлено, что максимальная степень набухания в воде убывает в ряду: отвердитель на основе карданола &gt; диэтилтолуолдиамин &gt; метилен-бис(орто-этиланилин), тогда как в о-ксилоле последовательность меняется: карданольный отвердитель &gt; метилен-бис(орто-этиланилин) &gt; диэтилтолуолдиамин. Рассчитанные значения критерия Флори-Хаггинса свидетельствуют, что термодинамическая совместимость напрямую зависит от наличия полярных групп в структуре отвердителя. Наибольшая сорбция воды и о-ксилола зафиксирована для полимера с сшивающим агентом на основе карданола, что объясняется присутствием гидроксильной группы и длинного алифатического фрагмента. Методом ДСК установлено, что температура стеклования для полимера на основе диэтилтолуолдиамина после экспозиции в агрессивных средах не претерпела существенных изменений.</p></abstract><kwd-group xml:lang="ru"><kwd>эпоксидно-фенольная смола</kwd><kwd>полиаминный отвердитель</kwd><kwd>сорбция</kwd><kwd>термодинамическая совместимость</kwd><kwd>химическая стойкость.</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">Студеникина Л.Н., Домарева С.Ю., Голенских Ю.Е., Матвеева А.В.
