Sulfonated Polyacrylic Acid Copolymer

CAS No.  40623-75-4

Structural Formula:

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

Properties:

Sulfonated Polyacrylic Acid Copolymer is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid. Due to including carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity) in this copolymer, Sulfonated Polyacrylic Acid Copolymer 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. Sulfonated Polyacrylic Acid Copolymer is suitable to be used in water quality of high pH and high alkaline, it is one of the ideal scale inhibitors and dispersants on high concentration index.

Specification:

Items Index
Appearance Colorless to light yellow viscous liquid Colorless to light yellow viscous liquid
Solid content % 30.0 min 40.0 min
Free monomer (as AA)% 0.50 max 0.50 max
Density (20℃)g/cm3 1.10 min 1.15 min
pH(1% water solution) 3.0 max 3.5-4.5

Usage:

Sulfonated Polyacrylic Acid Copolymer 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.

Sulfonated Polyacrylic Acid Copolymer can also be used as dyeing auxiliaries for textile.

Package and Storage:

Sulfonated Polyacrylic Acid Copolymer liquid: 200L plastic drum,IBC(1000L),customers’ requirement.

Sulfonated Polyacrylic Acid Copolymer solid: 20kg/bag,customers’ requirement. Storage for twelve months in shady room and dry place.

Synonyms:

AA-AMPS; AA-AMPSA; Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer; Sulfonated Polyacrylic Acid Copolymer;
