Product Description

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

CAS: 40623-75-4

Structural formula:

丙烯酸-2-丙烯酰胺-2-甲基丙磺酸共聚物（AA/AMPS）结构式

1. Performance and use:

AA/AMPS is a copolymer of acrylic acid and 2-acrylamide-2-methylpropanesulfonic acid (AMPS). Because the molecular structure contains carboxylic acid groups with good scale-inhibiting and dispersing properties and highly polar sulfonic acid groups, it can improve calcium tolerance and has a significant scale-inhibiting effect on calcium phosphate, calcium carbonate, zinc scale, etc. in the water, preventing The deposition of iron oxide, especially calcium phosphate, has a high scale inhibition rate. And it has excellent dispersion performance. Compounded with organic phosphine, the synergistic effect is obvious. It is especially suitable for water quality with high pH, high alkalinity and high hardness. It is one of the ideal scale inhibitor and dispersants to achieve high concentration multiple operation.

AA/AMPS can also be used as textile printing and dyeing auxiliaries; scale inhibitor for pulp in papermaking systems.
