Beschreibung
Zusammenfassung:	Novel polymers of a) 2-acrylamido-2- methylpropanesulphonic acid, b) acrylamide and/or methacrylamide, and c) acrylic acid and/or methacrylic acid especially salts thereof with, e.g., alkali ammonia, and amines are especially effective as treating agents for the prevention and/or removal of coating and encrustation on industrial plant apparatus such as boilers, turbines and pumps. The preferred polymers and salts comprise from 0.5 to 50% by weight of component (a), from 5 to 40% by weight of component (b) and have a molecular weight within the range of from 1,000 to 10,000.
