Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer
CAS No. 40623-75-4
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.
|Appearance||Colorless to light yellow viscous liquid||Colorless to light yellow viscous liquid|
|Solid content %||30.0 min||40.0 min|
|Free monomer (as AA)%||0.50 max||0.50 max|
|Density (20ºC)g/cm3||1.10 min||1.15 min|
|pH(1% water solution)||3.0 max||3.5-4.5|
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.
