CAS No. 40623-75-4
Structural Formula:
Properties:
AA/AMPS 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,
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 inhibitors and dispersants 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.
