Product Description

Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer

(AA/AMPS)

【CAS】40623-75-4

Synonyms: Sulphonated Polyacrylic Acid Copolymer, Dequest P9030

Structure:

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, it is one of the ideal scale inhibitor and dispersant on high concentration index.

Application:

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.
