Copolymer Comprising Monoethylenically Unsaturated Dicarboxylic Acid Derivatives

摘要

Copolymers which comprise dicarboxylic acid units modified with -SR, -CSNR₂ and/or -CN units, and also at least one further comonomer. Processes for preparing them by polymer-analogous reaction, and their use as corrosion inhibitors.
