Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer (AA/AMPS) 【CAS】 40623-75-4 Structural Formula: Properties: AA/AMPS is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS). 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, AA/AMPS is one of the ideal scale inhibitor and dispersant on high concentration index. Specification: items index Appearance Colorless or light yellow viscous liquid Solid content % 40 min Free monomer (as AA)% 0.8 max Density (20℃)g/cm3 1.15 min pH(1% solution) 3.5-4.5 Viscosity mpa.s 90-200 Usage: 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. Package and Storage: Normally In 250kg net Plastic Drum, IBC drum can also be used as required.Storage for ten months in room shady and dry place.
