AA/AMPS Copolymer

Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer

 AA/AMPS Copolymer

CAS No.: 40623-75-4

AA/AMPS is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS). Due to carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity), AA/AMPS has high calcium tolerance and good scale inhibition for calcium phosphate, calcium carbonate and zinc scale. When it is compounded with organophosphines, the synergic effect is obvious. AA/AMPS is suitable to use in water quality of high pH and high alkalinity, it is one of the ideal scale inhibitor and dispersant for high cycles of concentration.

AA/AMPS can be used as scale inhibitor and dispersant in open circulating cooling water system, oilfield refill water system, metallurgy system and iron & steel plants to prevent sediment of ferric oxide. When it is compounded 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.
