Abstract

PURPOSE: To enable to prevent and remove the scale without stopping the operation of plant, by using copolymer or its water soluble salt of itaconic acid having a specific component and unsaturated monomer of the other unsaturated carboxylic acid and other than said carboxylic acid.
CONSTITUTION: Another unsaturated carboxylic acid copolymerizing with itaconic acid, is acrylic acid, maleic acid etc. and unsaturated monomer other than said unsaturated carboxylic acid, is unsaturated sulfonic acid, such as styrene sulfonic acid, vinyl sulfonic acid. ≥75mol% itaconic acid and ≤25mol% unsaturated carboxylic acid and unsaturated monomer for copolymerization are used and polymerization is performed by the publicly known water sulubilizing polymerization. Molecular weight of said copolymer is limited within the range of 1,000W20,000. Further, water soluble salt is used for said copolymer and mixture of each salt of sodium, potassium, lithium etc. is used also.
