Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer(AA/AMPS) AA-AMPS AA-AMPSA
AA/AMPS is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid. 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.

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.
