Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer ( AA/ AMPS)
CAS No.: 40623-75-4
Molecular formula: [ C3H4O2] n[ C7H18NO4S] m
Structural Formula:

Product performance:
AA/ AMPS is the copolymer of acrylic acid and 2-acrylamide-2-methyl propanesulfonic acid ( AMPS) . Due to including carboxylic group ( scale inhibition and dispersion properties) and sulfonic acid group ( strong polarity) in this copolymer, AA/ AMPS has high calcium tolerance and good scale inhibition against calcium phosphate
calcium carbonate and zinc scale. The synergic effect is obvious when it is used together with organic phosphonic acid. AA/ AMPS is suitable to be used in water quality of high PH value and high alkaline, it is one of the ideal scale inhibitors and dispersants on high concentration index.
