Frequently Asked Questions

What is poly(2-acrylamido-2-methylpropanesulfonic acid)?

Poly(2-acrylamido-2-methylpropanesulfonic acid) (CAS 27119-07-9), often abbreviated PolyAMPS, is a strongly anionic sulfonated acrylamide polymer. It is used as a scale inhibitor and dispersant in water-treatment programs and as a rheology modifier in formulated systems. RawSource supplies it as an industrial polymer.

What is polyacrylamidomethylpropane sulfonic acid used for?

It controls mineral scale in cooling and process water, keeps particulate and mineral matter dispersed, modifies rheology to thicken and stabilize aqueous formulations, and provides sulfonate functionality as a co-monomer base for copolymer systems. Request the technical data for active content.

Is it an anionic polymer?

Yes — the sulfonic-acid (sulfonate) groups make it strongly anionic, which underpins its scale-inhibition and dispersant performance. CAS is 27119-07-9, HS code 3906.90. Request a CoA for grade-specific assay.

What forms and packaging does RawSource supply?

This polymer is typically supplied as an aqueous solution; available active content and packaging (drums, totes) depend on the lot. Confirm with your rep and request the SDS and CoA for documentation.

What is the cost of this polymer in bulk?

Bulk pricing depends on active content, packaging, and volume. RawSource quotes to spec — request a current bulk quote with your target quantity.
