Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid, Copolymer (AA/AMPS)
CAS No.:
40623-75-4
Structure Formula:
Properties:
AA/AMPS is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS). Due to including the 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 for use in water quality of high pH and alkaline. It is one of the ideal scale inhibitors and dispersants on a high concentration index.

Usage:
AA/AMPS can be used as a scale inhibitor and dispersant in open circulating cool water systems, oilfield refill water systems, metallurgy systems, and iron & steel plants to prevent sediment of ferric oxide. When built with organophosphorus and zinc salt, the suitable pH value is 7.0~9.5. AA/AMPS can also be used as dyeing auxiliaries for textiles.
Packing and Storage:
Normally in a 250 kg net plastic drum. IBC drum can also be used as required.
Storage for ten months in a room shady and dry place.
