Product Overview

2-Acrylamido-2-methylpropanesulfonic acid, widely known as AMPS, is a reactive hydrophilic sulfonic acid acrylic monomer supplied as a white crystalline powder or granular solid. Its strong anionic sulfonate group and sterically hindered amide structure make it a core building block for high performance water soluble polymers, widely used in water treatment, oilfield chemicals, construction admixtures, coatings and textile fiber modification.

Key Attributes

Key Highlights

• HIGH ASSAY MONOMER: Standard industrial assay of 99.0 percent minimum, with a 98 percent grade available for cost sensitive formulations, produced by a controlled Ritter reaction route for consistent batch quality.
• EXCELLENT HYDROLYTIC STABILITY: The geminal dimethyl group sterically shields the amide bond, so polymers built from this monomer keep their performance in hot, high salinity and alkaline service conditions.
• STRONG ANIONIC CHARACTER: The sulfonic acid group ionizes completely in water across a wide pH range, giving polymers stable charge density for scale inhibition and dispersion.
• BROAD COPOLYMERIZATION RANGE: Copolymerizes readily with acrylamide, acrylic acid, acrylonitrile, styrene, vinyl acetate and N-vinylpyrrolidone, supporting both homopolymer and tailor made copolymer synthesis.
• HARD WATER TOLERANCE: Polymers containing even a small share of this monomer strongly suppress precipitation of calcium, magnesium, iron, aluminium, zinc and barium salts.
• INDUSTRIAL SCALE SUPPLY: Bulk tonnage capacity with 25 kg bags, 25 kg drums and 1000 kg jumbo bags; minimum order quantity of 1 metric ton and shipment within 3 weeks of order confirmation.
• DOCUMENTATION READY: Certificate of analysis issued with every batch, plus technical data sheet and specification support for your qualification program.

Product Description

AMPS is a white crystalline solid monomer that combines a polymerizable acrylamide group with a strongly acidic sulfonic acid function. It is supplied at 99.0 percent minimum assay as the standard industrial grade, and as a 98 percent grade for applications where the balance of cost and performance matters more than maximum purity. The material is free flowing and easy to meter into aqueous or polar solvent polymerization systems.

Two structural features define its value. First, the two methyl groups on the alpha carbon shield the amide linkage, which dramatically slows hydrolysis and lets the resulting polymers survive elevated temperature and long term aqueous service. Second, the sulfonate group is a strong acid that stays fully ionized over a wide pH window, so charge density does not collapse in alkaline or high ionic strength media. Together these give AMPS based polymers excellent thermal stability, salt tolerance, calcium binding capacity and water absorption, which is why the monomer is used wherever a polymer has to keep working in a hostile aqueous environment.

Dideu supplies this monomer in bulk quantities for polymer producers, water treatment formulators and oilfield chemical blenders. The minimum order quantity is 1 metric ton, standard lead time is within 3 weeks after order confirmation, and goods move by sea in moisture proof packaging. Our quality team issues a certificate of analysis for every production batch and can align specification items with your incoming inspection standard.

Packaging and Shipping

Storage Recommendations

• Keep containers tightly sealed, since the product absorbs moisture readily from humid air.
• Store in a cool, dry and well ventilated warehouse, below 30 C where possible.
• Protect from direct sunlight and keep away from heat sources and hot surfaces.
• Handle opened packages on a first in first out basis and reseal partial bags immediately after use.

Transport mode: By sea for full container and bulk orders; air freight available for small pack orders. Lead time: Within 3 weeks after order confirmation. Minimum order quantity: 1 metric ton.

FAQ

1. What is the minimum order quantity?

The standard minimum order quantity from Dideu is 1 metric ton for bulk orders. Small pack sizes of 1 kg, 5 kg and 10 kg are also available.

2. What is the lead time?

Orders are normally shipped within 3 weeks after order confirmation. For repeat orders we can build buffer stock to shorten the cycle.

3. What packaging options do you offer?

We pack in 25 kg moisture proof bags, 25 kg drums with inner liner, and 500 kg or 1000 kg jumbo bags. Because the product is hygroscopic, all packagings include a moisture barrier liner.

4. What payment terms do you accept?

We accept T/T and L/C. For long term cooperation, payment terms can be discussed based on order history and volume.

5. Do you provide a certificate of analysis and technical documents?

Yes. Every batch is shipped with a certificate of analysis covering assay, appearance, melting point and the other items agreed in the specification. A technical data sheet is also available on request.

6. How do you ship the goods?

Bulk orders are shipped by sea in full container loads or less than container load, with jumbo bags or palletized drums according to your preference. Small pack orders can go by air freight or international courier.

7. Can you match a specification we already use?

Yes. Send us your current specification sheet or incoming inspection standard, and Dideu will confirm which items we test, align the certificate of analysis format, and add extra test items such as particle size or color where required.
