Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid
Copolymer (AA/AMPS)

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.

Specification:

items Index
Appearance Colorless or light yellow viscous liquid
Solid content ≥40%
Free monomer (as AA) ≤0.8%
Density (20℃) ≥1.15 g/cm3
pH(1% solution) 3.5-4.5
Viscosity 90-200 mpa.s

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.

Package and Storage:

Normally In 250kg net plastic drum. IBC drum can also be used as required. Storage for ten months in room shady and dry place.
