AA/AMPS

Product Details

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

AA/AMPS

CAS Number: 40623-75-4

Molecular Formula:[C3H4O2]n[C7H18NO4S]m 

Application Notes:

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.

Recommended Uses:

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.
