CAS No.: 40623-75-4
AA/AMPS is the copolymer of acrylic acid and 2-acrylamide-2-methylpropane sulfonic 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 copolymer is suitable to be used in water quality of high pH and high alkaline. AA/AMPS copolymer is one of the ideal scale inhibitor and dispersant on high concentration index.
|Appearance||Colorless or light yellow liquid|
|Solid content %||40 min|
|Free monomer (as AA)%||0.8 max|
|Density (20℃)g/cm3||1.15 min|
|pH(1% water solution)||3.5-4.5|
AA/AMPS can be used as a 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 organophosphine and zinc salt, the suitable pH value is 7.0~9.5.
AA/AMPS copolymer can also be used as dyeing auxiliaries for textile.
