The landscape of polymer science is constantly evolving, driven by the demand for materials with enhanced functionalities. Sulfonated monomers, in particular, have garnered significant attention for their ability to impart unique properties like hydrophilicity, ionic conductivity, and improved solubility. Among these, 2-Sulfoethyl Methacrylate (SEMA), CAS 10595-80-9, stands out. As a leading manufacturer and supplier in China, we provide this critical building block to drive innovation across various industries.

What Makes Sulfonated Monomers Special?

Sulfonic acid groups (-SO₃H) are strongly acidic and highly polar, making them powerful functional groups in polymer chemistry. When incorporated into a polymer chain, these groups can:

  • Increase Water Solubility: The polar nature of the sulfonate group enhances the polymer's affinity for water, making it ideal for water-soluble polymers, hydrogels, and aqueous dispersions.
  • Provide Ionic Conductivity: Sulfonated polymers act as polyelectrolytes, facilitating the movement of ions. This property is crucial for applications such as ion-exchange membranes, solid polymer electrolytes, and antistatic coatings.
  • Enhance Adhesion: The polarity can also lead to improved adhesion to various substrates, especially those with polar surfaces, which is beneficial in coatings and adhesives.
  • Offer pH Responsiveness: The ionization state of the sulfonic acid group can change with pH, allowing for the development of smart materials that respond to environmental stimuli.

2-Sulfoethyl Methacrylate: A Versatile Sulfonated Monomer:

2-Sulfoethyl Methacrylate (SEMA) expertly combines a polymerizable methacrylate functionality with a pendant sulfoethyl group. This dual nature allows it to be readily incorporated into polymer backbones via conventional polymerization techniques. Its molecular formula is C₆H₁₀O₅S, with a molecular weight of 194.21 g/mol. As a trusted manufacturer and supplier from China, we ensure that our SEMA is of high purity, typically 97%+, making it suitable for demanding applications where quality and performance are paramount. For businesses looking to buy SEMA, partnering with us offers advantages in cost-effectiveness and supply chain reliability.

Key Applications Driven by SEMA:

  • Biomaterials: In the development of biocompatible hydrogels for drug delivery, tissue engineering, and ophthalmic applications.
  • Coatings: For improving adhesion, water resistance, and anti-fouling properties in industrial and architectural coatings.
  • Water Treatment: As a component in flocculants, dispersants, and ion-exchange resins.
  • Electronics: In conductive polymers, antistatic coatings, and materials for advanced battery technologies.
