    Abstract: The present invention relates to a process for preparing (meth)acrylic esters (F) of N,N-substituted amino alcohols, by transesterifying N,N-substituted amino alcohols (I) in which Y and Z are each independently C1-C20-alkyl, C3-C15-cycloalkyl, aryl, or Y and Z together with the nitrogen atom connecting them form a 5- to 9-membered saturated heterocyclic radical which optionally has oxygen, sulfur, nitrogen or C1-C4-alkyl-substituted nitrogen as a further heteroatom, and X is C2-C20-alkylene which may be interrupted by 1 to 10 nonadjacent oxy groups and/or unsubstituted or methoxy-substituted C1-C4-alkylimino groups, or C3-C15-cycloalkylene, with at least one (meth)acrylic ester (D) in the presence of at least one heterogeneous catalyst (K), wherein the heterogeneous catalyst (K) is used without any further solvent and the content of polymerization inhibitors in the reaction mixture is

    Abstract: Method of applying corrosion control coats, especially integrated pretreatment layers or coats for atmospheric corrosion control, to metallic surfaces, using copolymers comprising as monomeric building blocks 20% to 70% by weight of monomers containing nitrogen heterocycles, 10% to 50% by weight of monomers containing acidic groups, 10% to 50% by weight of vinylaromatic monomers, and optionally 0% to 25% by weight of further monomers. Copolymers of the stated composition, and also preparations for applying corrosion control coats.
