Сopolymers and the 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.
