Merck, 282731-250G, 2-Acrylamido-2-methyl-1-propanesulfonic acid

General description
2-Acrylamido-2-methyl-1-propanesulfonicacid (AMPS) is a reactive and hydrophilic monomer that belongs to the class of sulfonic acid acrylic monomers. It is used in the synthesis of various polymers such as poly(2-acrylamido-2-methylpropanesulfonic acid-CO-acrylic acid), poly(acrylamidomethylpropanesulfonic acid-co-acrylicacid), and poly(acrylic acid-co-2-acrylamido-2-methyl propane sulfonic acid). These polymers are used in a wide range of applications, such as textiles, flocculants, dispersants, scale control agents, personal care products, water treatment, oil fields, and emulsion coatings. AMPS has an ionic character due to the sulfonic acid group, which is valuable for applications such as ion exchange, flocculation, and water treatment.
Application
2-Acrylamido-2-methyl-1-propanesulfonic acid can be used as a monomer:

• In the synthesis of polyampholyte hydrogels for Potential Biomedical Applications, including tissue engineering, drug delivery, antibacterial and antifouling materials.
• To graft bacterial cellulose membranes for fuel cell applications. AMPS potentially improves the proton conductivity and fuel cell application of the bacterial cellulose membranes.
• In the preparation of a superabsorbent hydrogel. The presence of AMPS enhances the superabsorbent properties, which are important for applications such as wastewater treatment, wound healing medical devices, and agriculture.
• In the formation of a polyelectrolyte with enhanced electrochemical properties for supercapacitor applications.
