1. Scientific Research and New Material Development

Used as a monomer for synthesizing high-molecular-weight polymers with specific functions. These polymers can be used in biomedical materials (such as antithrombotic coatings, tissue engineering scaffolds), water treatment adsorbents, high-toughness hydrogels, nanocomposite materials, etc.

2. Textile and Chemical Fiber Industry

Used as a third monomer in the dry spinning process of acrylic fibers (polyacrylonitrile fibers) to improve the dyeing properties of the fibers. Also used as a dyeing modifier and antistatic agent.

3. Functional Additives

Used as a reactive emulsifier in emulsion polymerization; used as an antistatic agent in nylon, polyester, recording paper, and other materials.
Utilizes the hydrophilicity and ionic conductivity of its sulfonic acid group.

4. Water Treatment

Can be used as a raw material or component in the preparation of water treatment agents.

5. Daily Chemical Products

In commercial information, it is listed as a cosmetic ingredient and a chemical for hair products.

6. Other Industrial Applications

Used in the preparation of ion exchange resins, electroplating brighteners, photographic chemicals, etc.
