Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer
(AA/AMPS)
【CAS】40623-75-4
Synonyms: Sulphonated Polyacrylic Acid Copolymer, Dequest P9030
Structure:
Properties:
AA/AMPS is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS).
Due to including carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong
polarity) in this copolymer, AA/AMPS has high calcium tolerance and good scale inhibition for
calcium phosphate, calcium carbonate and zinc scale. When built with organophosphines, the
synergic effect is obvious. AA/AMPS is suitable to be used in water quality of high pH and high
alkaline, it is one of the ideal scale inhibitor and dispersant on high concentration index.

Application:
AA/AMPS can be used as scale inhibitor and dispersant in open circulating cool water system,
oilfield refill water system, metallurgy system and iron & steel plants to prevent sediment of ferric
oxide. When built with organophosphorines and zinc salt, the suitable pH value is 7.0~9.5. AA/AMPS
can also be used as dyeing auxiliaries for textile.
