Copolymer
CAS 40623-75-4

Properties of AA/AMPS:
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 of AA/AMPS:
Appearance Colorless or light yellow viscous liquid
Solid content % 40 min
Free monomer (as AA)% 0.8 max
Density (20 C)g/cm3 1.15 min
pH(1% solution) 3.5-4.5
Viscosity mpa.s 90-200

Usage of AA/AMPS:
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 of AA/AMPS:
Normally In 250kg net Plastic Drum, IBC drum can also be used as required.Storage for ten months in
room shady and dry place.
