It is shown that the introduction of BS-50 in the optimum concentration of nanoparticles into DER-330 epoxy resin results in agglomeration, which is accompanied by an abnormal behavior of the disperse system with a decrease in viscosity by ~ 25%, ultimate shrinkage by ~ 15% and the level of residual stresses by a factor of ~ 4-10. These properties are manifested when the concentration of fumed silica is 0.05 vol. % The introduction of fumed silica slows the rise of residual stresses and increases the induction period from 2 to 4 hours. Depending on the mode of curing the minimum residual stress is observed at different concentrations of BS-50. At temperatures of 30ºC and 50°C concentration was 0.5 vol. %, and at 70°C - 0.05 vol. %. Curing at 30°C and 50°C result in a fall of residual stress by a factor of 12 and 4, respectively, at 70°C, by a factor of 4.</p></abstract><trans-abstract xml:lang="ru"><p>Рассматривается влияние наночастиц диоксида кремния в виде белой сажи марки БС-50 на реологические свойства, усадку и усадочные остаточные напряжения при отверждении эпоксидного олигомера. Показано, что при введении наночастиц БС-50 в оптимальной концентрации в эпоксидный олигомер марки DER-330 наблюдается их агломерация, которая сопровождается аномальным поведением дисперсной системы со снижением вязкости на ~25%, конечной усадки на ~15% и уровня остаточных напряжений - примерно в 4-10 раз. Снижение вязкости, усадки и остаточных напряжений (при 70ºС) наблюдается при введении 0.05% об. белой сажи.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эпоксидный олигомер</kwd><kwd>наночастицы</kwd><kwd>белая сажа</kwd><kwd>нанокомпозит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>epoxy resin</kwd><kwd>nanoparticles</kwd><kwd>fumed silica</kwd><kwd>nanocomposite</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">Полимерные нанокомпозиты / под ред.
