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.

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 textiles.
package and storage:
normally 250kg net in drum, ibc, or as required. storage for ten months in shady room and dry places.
