Abstract (en)
Use of telomers formed from telogens containing mercaptan groups and acrylic compounds as scale and/or corrosion inhibitors. Telomers of the general formula <IMAGE> or <IMAGE> where R is an aliphatic radical of 2 to 22 carbon atoms which may contain one or more carboxyl and/or hydroxyl groups, X is H or methyl, M is an alkali metal ion, and n and m are integers of a magnitude such that the telomers have an average molecular weight between 300 and 3000, in particular 700 to 2000, and where some of the nitrile groups can also be hydrolysed to amide groups, as scale and/or corrosion inhibitors in industrial process water systems instead of phosphorus- containing substances in an amount of 0.1 to 100, in particular from 1 to 30, ppm, based on the process water.
