Abstract — Experimental data on the influence of the film-forming polymer on the effectiveness of polymeric coatings on metals are discussed. Polystyrene, poly(butyl methacrylate), and copolymers of butyl methacrylate and styrene with 2-vinylpyridine (BMAVP and SVP) were used as film-forming polymers for the coatings. The correlation between the composition of the film-forming polymers, the properties of the coatings (adhesion and permeability), the coating functions (metal corrosion under the coatings), and the coating inhibition factor was studied. A criterion for the latter was proposed. According to the data obtained, the inhibited coatings prepared from the copolymers BMAVP-5, SVP-5, and SVP-10 (containing 5 and 10% VP) were most effective.
