CAS No. 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, it is
one of the ideal scale inhibitor and dispersant on high
concentration index.

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.
