Use

1. Water Treatment and Flocculants

• Raw Material for Water Treatment Agents: Serves as a monomer in synthesizing high-molecular flocculants, dispersants, or scale inhibitors. For example, copolymerization with monomers like acrylamide and acrylic acid yields efficient water treatment agents, used in industrial wastewater treatment and drinking water purification to remove suspended solids, heavy metal ions, and organic matter through adsorption and bridging effects.
• Sludge Dewatering Aid: In sludge treatment, its polymeric products improve sludge dewatering performance and enhance dewatering efficiency.

2. Polymer Synthesis and Modification

• Special Polymer Material Monomer:
  • Used to prepare salt-resistant and temperature-resistant polymer materials, such as oilfield flooding agents (to enhance oil recovery). The sulfonic acid groups endow polymers with hydrophilicity and salt resistance, adapting to high-salinity reservoir environments.
  • Acts as a functional monomer for synthesizing water treatment membranes and ion-exchange resins, enhancing the ion-exchange capacity of resins or the selective permeability of membranes by introducing sulfonic acid groups.
• Coating and Adhesive Modification: Added to acrylate coatings or adhesives to improve water resistance, adhesion, and anti-aging properties, commonly used in architectural coatings and metal surface treatment agents.

3. Oilfield Chemistry and Petroleum Industry

• Drilling Fluid Additive: Functions as a fluid loss reducer or flow pattern regulator in drilling fluids, improving their stability, reducing water penetration, and preventing wellbore collapse.
• Acidizing and Fracturing Aid: In oilfield acidizing operations, its derivatives can serve as corrosion inhibitors or flowback agents to reduce acid corrosion on equipment and promote residual fluid discharge.

4. Textile and Dyeing Industry

• Raw Material for Dye Fixatives: Copolymerized with other monomers to form fixatives for reactive dyeing, enhancing the binding force between dyes and fibers and reducing chroma and pollutant discharge in dyeing wastewater.
• Antistatic Finishing Agent: The hydrophilicity of its sulfonic acid groups imparts antistatic properties to textiles, often used in post-treatment of chemical fiber fabrics.

5. Paper Industry

• Paper Strengthening Agent: Participates in synthesizing wet or dry strength agents to improve paper strength and water resistance, suitable for packaging paper and special industrial paper.
• Retention and Filtration Aid: Through charge neutralization and bridging effects, it improves the retention rate of fillers and fine fibers and optimizes the water filtration performance in the papermaking process.

6. Other Applications

• Pharma-ceutical and Cosmetic Intermediates: Serves as an organic synthesis intermediate for preparing certain drugs or cosmetic additives (e.g., those with moisturizing and antistatic properties).
