Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer (AAAMPS)
CAS No. 40623-75-4
Structural Formula:
Properties:
Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer is the copolymer of acrylic acid and 2-acrylamide-2-methyl propane sulfonic acid (AMPS). Due to including carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity) in this copolymer, AAAMPS 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 a high concentration index.

Usage:
AAAMPS 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 ferric oxide sediment. When built with organophosphorus and zinc salt, the suitable pH value is 7.0~9.5.
AAAMPS can also be used as dyeing auxiliaries for textile.
