Abstract

The present invention relates to a method of applying atmospheric corrosion control coats to metallic surfaces, using copolymers comprising as monomeric building blocks monomers containing nitrile groups, monomers containing acidic groups, and vinylaromatic monomers. It relates, furthermore, to preparations for applying corrosion control coats.
