Установлено, что высокодисперсные частицы MgO участвуют в процессе полимеризации и выступают как дополнительные узлы сшивки дефектных областей полимерной сетки, что улучшает функциональные свойства порошковых эпоксидных композиций. Покрытия на основе модифицированных композиций характеризуются высокими физикомеханическими показателями при низкотемпературном отверждении (130 °С) и могут быть использованы для формирования защитных покрытий на термочувствительных изделиях.</p></abstract><trans-abstract xml:lang="en"><p>The process of forming epoxy powder compositions with the participation of highly dispersed magnesium oxide in the preparation of compositions by extrusion mixing of components in the melt is investigated. It is established that highly dispersed MgO particles participate in the polymerization process and act as additional crosslinking units of defective regions of the polymer network, which improves the functional properties of epoxy powder compositions. Coatings based on modified compositions are characterized by high physicomechanical properties at low temperature curing (130 °С) and can be used to form protective coatings on heat-sensitive products.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>порошковые эпоксидные композиции</kwd><kwd>оксид магния</kwd><kwd>размер частиц</kwd><kwd>температура стеклования</kwd><kwd>физико-механические свойства покрытий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>epoxy powder composition</kwd><kwd>magnesium oxide</kwd><kwd>particle size</kwd><kwd>glass transition temperature</kwd><kwd>physical and mechanical properties of coatings</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">Chen, C.
