Potassium 3-Sulfopropyl Acrylate, identified by CAS number 31098-20-1, is a highly functional anionic monomer that integrates a reactive acrylate group with a hydrophilic sulfonic acid potassium salt. This unique chemical architecture facilitates its participation in free-radical polymerization, allowing for the seamless incorporation of ionic sites into various polymer backbones. As a crystalline solid, it exhibits excellent solubility in water and polar solvents, making it a preferred choice for aqueous-based synthesis. Proper handling involves maintaining dry conditions, as the material is sensitive to moisture and atmospheric humidity.
In industrial and research contexts, this compound is prized for its ability to significantly alter the physical and chemical properties of materials. By introducing sulfonate groups, it enhances the hydrophilicity, thermal stability, and ionic conductivity of copolymers. Its versatility makes it a cornerstone in the development of advanced functional polymers, providing researchers with a reliable tool for tailoring surface energy and charge density in complex chemical systems.
