FIELD: polymeric protective coatings. ^ SUBSTANCE: invention relates to compositions forming anticorrosive coatings on reinforced concrete, concrete, and bricks and which, in particular, can be employed for anticorrosive protection of concrete floors, large-size metallic containers, pipelines, brick basements, bottoms, cattle-breeding farms, open-type swimming pools, and also air conduits, piping, and other metallic structures in industrial buildings, and near production enterprises producing corrosive emissions into atmosphere. Coating according to invention is composed by copolymer obtained via copolymerization of vinyl ether with methyl methacrylate at weight ratio (3-6):1 in presence of azo-bis-isobutyronitrile followed by dissolution of copolymer in toluene. Vaporization of the latter leaves film protecting surface from destruction. ^ EFFECT: enhanced protection efficiency. ^ 10 tbl |
