Characteristics:

2-Acrylamido-2-Methylpropane Sulfonic Acid (AMPS) is a kind of vinyl monomer that contains sulfonic acid gene. Its structure contains strong anionic, water-soluble sulfur-based groups, shielded amide groups and unsaturated double bond, so that it has an excellent overall performance, good complex nature of complexation, adsorption, biological activity, surface activity, hydrolytic stability and thermal stability. In aqueous solution, AMPS monomer has a very slow rate of hydrolysis, and its sodium aqueous solution has an excellent anti-hydrolysis performance when the pH is greater than 9. In acidic conditions, the anti-hydrolysis performance of AMPS homopolymer is much higher than that of polyacrylamide.

Applications:

AMPS is used in many areas due to its nature of both copolymerization and homopolymerization, including oilfield chemistry, water-treatment, synthetic fibers, printing and dyeing, plastic, paper-making, water-absorbent coatings, biomedical, magnetic materials and cosmetics .

1. Water treatment: Homopolymer of AMPS monomer or copolymers with acrylamide, acrylic acid monomer, could be as sludge dehydrating agent in the sewage purification process. As preservatives of the iron, zinc, aluminum, cooper and alloy in the closed water circulation systems, they also could be used as cleaning and inhibitor of heater, cooling towers, air purifiers and gas purification device.

2. Oilfield chemistry: This product is developed rapidly in the application of the oilfield chemistry. Application field covers such as oil well cement additives, treatment agent of drilling fluid, acidizing fluids, fracturing fluids, completion fluids and workover fluids additives.

3. Synthetic fibers: The AMPS is an important monomer which could change the combination property of some synthetic fiber, particularly in the orion and the modacrylic fiber with chloride, and the dosage is the 1%-4% of the fiber. It could significantly improve the fiber whiteness,dyeability,antistatic,permeability and flame resistance properties.

4. Textile pulp: 2 - acrylamido -2 - methyl-propanesulfonic acid and ethyl acetate and acrylic acid copolymer is ideal slurry of cotton and polyester blended fabric, with the characteristics of using easily and being removed easily by water.

5. Paper making: The copolymer of 2 - acrylamido -2 - methyl-propane sulfonic acid and other water-soluble monomer is an indispensable chemical for all kinds of paper making factories, which can be used not only as drainage aids, the adhesives, increasing the strength of paper, but also be used as color-coated pigment dispersant.

Use Method:

Method and amount of 2-acrylamido-2-methyl-propanesulfonic acid varies in various application fields, and it is determined based on product characteristics by experts.
