General description

2-Acrylamido-2-methyl-1-propanesulfonic acid sodium salt (AMPS Na) is a monomer that belongs to the class of sulfonic acid monomers. It is commonly used in the production of various polymers, such as polyacrylamide co-polymers, poly(AMPS), AMPS-functionalized polymers, and hydrogels . These polymers are used in paints, adhesives, textiles, paper manufacturing, personal care products, coating, and adhesive applications. Additionally, AMPSNa also serves as a comonomer in combination with other acrylic monomers to enhance the scrub resistance and dispersant performance of paper coatings and paint emulsions. It can be used as a dopant and a protonating agent for conducting polymers. It is used in a variety of electronic applications.

Application

2-Acrylamido-2-methyl-1-propanesulfonic acid sodium salt (AMPS Na) can be used:
  • As a monomer in the formation of polyelectrolyte copolymer gels for potential application in bioengineering, biomedicine, and water purification .
  • In the fabrication of Schottky diodes, humidity sensors, and lithium-ion batteries.
  • As a monomer in the synthesis of a hydrogel nanocomposite applicable as a potential adsorbent for dyes .
