The Copolymer of Phosphono and Carboxylic Acid (PCA) is a water-soluble polymer that contains both phosphonic and carboxylic acid functional groups. It is used primarily as a scale inhibitor, dispersant, and corrosion inhibitor in various applications such as water treatment, detergents, and industrial processes. The dual functionality of phosphono and carboxylic acid groups enhances its performance in preventing mineral buildup and corrosion in industrial systems.
