| abstract | TITLE OF THE INVENTION CARBOXYLIC/SULFONIC/QUATERNARY AMMONIUM POLYMERS FOR USE AS SCALE AND CORROSION INHIBITORS ABSTRACT OF THE DISCLOSURE The instant invention is directed to a process for inhibiting corrosion and the formation and deposition of scale in aqueous systems, comprising adding to the system at least 0.1 ppm of a water-soluble polymer having an intrinsic viscosity of 0.05 to 2.5, prepared from: (a) 50 to 90%, by weight, of an unsaturated carboxylic acid, or its salt; (b) 5 to 40%, by weight, of an unsaturated sulfonic acid, or its salt; and (c) 5 to 40%, by weight, of an unsaturated quaternary ammonium compound. The instant invention is also directed to a water soluble polymer, having an intrinsic viscosity of 0.05 to 2.5 prepared from: (a) 50 to 90%, by weight, of an unsaturated carboxylic compound selected from the group consisting of acrylic acid, methacrylic acid, their salts and mixtures thereof; (b) 5 to 40%, by weight, of an unsaturated sulfonic compound selected from the group consisting of 2-acrylamido-2-methylpropylsulfonic acid, 2-methacrylamido 2-methylpropyl sulfonic acid, their salts and mixtures thereof; and (c) 5 to 40%, by weight, dimethyl diallyl ammonium chloride, diethyl diallyl ammonium chloride and mixtures thereof. |
