In this study, copolymers were obtained and their synthesis procedure was refined to produce protective polymer coatings. Different fillers were selected for obtaining polymer coating, such as silicon production waste (microsilica) and titanium dioxide, as well as the combination thereof. Two copolymers (No. 1 and No. 2) and seven series of polymer coatings were developed. The obtained polymers exhibit good adhesion, which is a requirement for composite protective coatings. An experiment was conducted to determine the corrosion resistance of metals exposed to aggressive media, and to determine the hardness and thickness of the resulting polymer coatings. For example, a corrosion score of 2 was achieved for the polymer coating with titanium dioxide filler exposed to aggressive media (5% NaCl and 5% KOH solutions), while a corrosion score of 3–4 was achieved in acidic and 10% KOH media. A polymer coating with microsilica filler demonstrated a corrosion score of 2 in saline and acidic aggressive media, while such coating underperformed in alkaline media, exhibiting a corrosion score of 4. The best corrosion resistance values are demonstrated by the combined styrene polymer coating, consisting of methyl methacrylate and butyl vinyl ether, with a corrosion score of 2 in saline and acidic media and a corrosion score of 4 in alkaline media. The combined coating, consisting of methyl methacrylate, maleic anhydride, and butyl vinyl ether, shows the worst corrosion resistance characterized by corrosion scores of 4, 5, and 6 in 10% H₂SO₄ and alkaline media (5 and 10% KOH), respectively. At the same time, the developed polymer coatings have satisfactory adhesion properties even after exposure to aggressive media.
