Characteristics:

2-Acrylamido-2-Methylpropane Sulfonic Acid (AMPS) is a kind of vinyl monomer that contains sulfonic acid gene. Its structure contains strong anionic, water-soluble sulfur-based groups, shielded amide groups and unsaturated double bond, so that it has an excellent overall performance, good complex nature of complexation, adsorption, biological activity, surface activity, hydrolytic stability and thermal stability. In aqueous solution, AMPS monomer has a very slow rate of hydrolysis, and its sodium aqueous solution has an excellent anti-hydrolysis performance when the pH is greater than 9. In acidic conditions, the anti-hydrolysis performance of AMPS homopolymer is much higher than that of polyacrylamide.
