Description

Copolymerofacrylicacidand2-Acrylamido-2-Methylpropylsulfonicacid CAS NO 97953-25-8 is a high-performance, water-soluble anionic copolymer synthesized from acrylic acid (AA) and 2-acrylamido-2-methylpropane sulfonic acid (AMPS). This unique copolymer is engineered to provide exceptional scale inhibition and dispersancy, particularly in high-temperature and high-hardness aqueous environments. It is a critical additive for industries requiring robust water treatment, enhanced oil recovery, and superior detergent formulations.

Application

• Industrial Water Treatment: Primary application as a highly effective scale inhibitor and dispersant for calcium carbonate, calcium sulfate, and barium sulfate in cooling water, boiler water, and reverse osmosis systems.
• Oilfield Chemicals: Used in drilling fluids, completion fluids, and enhanced oil recovery (EOR) operations for its superior thermal stability and salt tolerance to control scale and improve fluid performance.
• Detergents & Cleaners: Functions as a builder and anti-redeposition agent in liquid and powder detergents, improving cleaning efficiency by sequestering hardness ions and dispersing soil.
• Pulp & Paper Industry: Acts as a dispersant and retention aid in papermaking processes, helping to control pitch and stickies while improving sheet formation.
• Textile Processing: Employed as a dye dispersant and anti-precipitant to ensure uniform dyeing and prevent scale buildup on machinery.
• Construction Chemicals: Incorporated into cement admixtures and gypsum slurries as a superplasticizer and water reducer to improve workability and final strength.

Quality Control

Our AA/AMPS copolymer is manufactured under a strict quality management system. Every batch undergoes rigorous testing for key parameters including solid content, viscosity, pH, and residual monomers to ensure consistent performance. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption and caking. Keep away from incompatible materials such as strong oxidizing agents.
