Import Amps Monomer — Buy in Bulk from Supplier in China

2-Acrylamido-2-methylpropane sulfonic acid (AMPS monomer) is a vinyl monomer distinguished by its sulfonic acid functional group, with the CAS number 15214-89-8 and molecular formula C7H13NO4S. The structural formula CH2=CHCON2 confirms its reactive double bond, enabling both homopolymerization and copolymerization. This monomer exhibits strong resistance to hydrolysis in acidic conditions, with its multipolymer outperforming polyacrylamide in anti-hydrolysis stability under low pH.

The material combines high surface activity, complexation, and absorption properties, making it suitable for applications requiring thermal and hydrolytic stability. Its sodium salt form maintains anti-hydrolysis performance even at high pH, while the monomer itself has a low hydrolytic rate in aqueous solutions. Standard purity for AMPS monomer in industrial grades is typically above 98%, with a typical moisture content below 1% as per commodity specifications.

AMPS monomer is widely used in oilfield chemistry for enhanced oil recovery, water treatment as a scale inhibitor, and in the production of absorbents, coatings, and synthetic fibers. Buyers in the textile, paper, and biomedical sectors source it for its bioactivity and stability. Trade terms often include bulk packaging in 25 kg or 50 kg drums, with storage recommendations to avoid prolonged exposure to moisture and direct sunlight.
