Structural Formula:
Properties:
Acrylic Acid-2-Acrylamido-2-Methylpropane
Sulfonic 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,
Acrylic Acid-2-Acrylamido-2-Methylpropane
Sulfonic 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.
Acrylic Acid-2-Acrylamido-2-Methylpropane
Sulfonic 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.

Usage:
Acrylic Acid-2-Acrylamido-2-Methylpropane
Sulfonic 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.
Acrylic Acid-2-Acrylamido-2-Methylpropane
Sulfonic Acid Copolymer can also be used as dyeing
auxiliaries for textile.
