methodology for their synthesis are presented. In order to protect metal products and structures from the effects of corrosion processes, various fillers for polymer coating were selected: silicon production waste (microsilica) and titanium dioxide, as well as their combined mixtures. The obtained copolymers exhibit good adhesion required for composite protective coatings. An experiment was conducted to evaluate the corrosion resistance of metals subjected to aggressive environment, as well as to determine the hardness and thickness of the obtained polymer coatings. Thus, the corrosion score of the polymer coating with titanium dioxide filler is 2 in 5% NaCl and 5% KOH aggressive media and is 3-4 in acidic media with 10% KOH. Polymer coating with microsilica filler has a corrosion score of 2 in salt and acid aggressive media, but in alkaline media such coating performed worse and has a corrosion score of 4. The best corrosion resistance values are for the series 2 combination polymer coating consisting of methyl methacrylate, styrene and vinyl butyl ether, with a corrosion score of 2 in salt and acid media and a corrosion score of 4 in alkaline media. Series 1, methyl methacrylate, maleic anhydride, and vinyl butyl ether combined coating has the worst corrosion resistance: corrosion score of 4, 5, 6 in 10% H2SO4 and in an alkaline media (5 and 10% KOH), respectively. At the same time, the developed polymer coatings exhibit satisfactory adhesion properties even after the exposure to aggressive media.</p></abstract><trans-abstract xml:lang="ru"><p>Представлены сополимеры и разработана методика их синтеза. Для полимерного покрытия были выбраны различные наполнители - отходы производства кремния (микрокремнезем) и диоксид титана, а также их комбинированные смеси с целью защиты металлических изделий и конструкций от воздействия коррозионных процессов. Полученные сополимеры обладают хорошей адгезией, необходимой для создания композитных защитных покрытий. Проведен эксперимент по определению коррозионной стойкости металлов под воздействием агрессивных сред, а также по определению твердости и толщины полученных полимерных покрытий. Таким образом, коэффициент коррозии полимерного покрытия с наполнителем из диоксида титана составляет 2 в агрессивных средах с содержанием 5 % NaCl и 5 % KOH и 3-4 в кислых средах с содержанием 10 % KOH. Полимерное покрытие с микрокремнеземным наполнителем имеет показатель коррозии 2 в солевых и кислотных агрессивных средах, но в щелочных средах такое покрытие работает хуже и имеет показатель коррозии 4. Наилучшие показатели коррозионной стойкости имеют комбинированные полимерные покрытия серии 2, состоящие из метилметакрилата, стирола и винилбутилового эфира, с показателем коррозии 2 в соленой и кислой средах и 4 в щелочной среде. Комбинированное покрытие серии 1, состоящее из метилметакрилата, малеинового ангидрида и винилбутилового эфира, обладает наихудшей коррозионной стойкостью: показатель коррозии составляет 4, 5, 6 10 % H2SO4 и щелочной среде (5 и 10 % KOH) соответственно. В то же время разработанные полимерные покрытия обладают удовлетворительными адгезионными свойствами даже после воздействия агрессивных сред.</p></trans-abstract><kwd-group xml:lang="en"><kwd>copolymer</kwd><kwd>polymer</kwd><kwd>polymer coating</kwd><kwd>protective coating</kwd><kwd>filler</kwd><kwd>microsilica</kwd><kwd>titanium dioxide</kwd><kwd>adhesion</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>сopolymer synthesis</kwd><kwd>синтез сополимера</kwd><kwd>сополимер</kwd><kwd>полимер</kwd><kwd>полимерное покрытие</kwd><kwd>защитное покрытие</kwd><kwd>наполнитель</kwd><kwd>микрокремнезем</kwd><kwd>диоксид титана</kwd><kwd>адгезия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Yakupov S.N., Gumarov G.G., Yakupov N.M.
