Агрегативная устойчивость систем латекс–TiO2 при увеличении концентрации дисперсной фазы растет, а для системы латекс–слюда падает. Введение ПАВ анионного и неионогенного типов в смешанные дисперсии (рН 6,7) приводит к повышению их диспергируемости. Повышение рН дисперсионной среды существенно улучшает диспергируемость порошков в латексах, не содержащих диспергаторы. </p></abstract><trans-abstract xml:lang="en"><p>Stability of water dispersions of a polyorganosiloxane and TiO2 or mica both in presence of surfactants and without them has been studied at pH 6.7 and 8.7 by nephelometry and granulometry. Aggregate stability of latex-TiO2 system increases with disperse phase concentration, while decreasing for the latex-mica system. Introduction of anionic and nonionic surfactants into mixed dispersions (pH 6.7) leads to increase. Increase of dispersant pH significantly improves dispersancy of powders in the latex without dispersing agent. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>водно-дисперсионная смешанная система</kwd><kwd>седиментационная стабильность</kwd><kwd>минеральный порошок</kwd><kwd>полиорганосилоксан</kwd></kwd-group><kwd-group xml:lang="en"><kwd>water dispersions composite system</kwd><kwd>sedimentation stability</kwd><kwd>mineral powder</kwd><kwd>(poly)organosiloxane</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">Flocculation of dilute titanium dioxide suspension by graft cationic polyelectrolytes / D.
