AA/AMPS 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 (h3 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.
Items Index Appearance Colorless to pale yellow viscous liquid Solid content, % 40.0 min Free monomer (as AA), % 0.5 max Density (20℃), g/cm3 1.15 min pH(1% water solution) 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.
