Introduction and Application

2-Acrylamide-2-methylpropanesulfonic acid is a white crystalline powder with a melting point of 185°C, a slightly sour taste, and strong hygroscopicity. If exposed to moisture, AMPS monomers will polymerize themselves. Its aqueous solution is acidic, soluble in dimethylamide, partially soluble in methanol and ethanol, and difficult to dissolve in acetone.

The AMPS structural formula contains a strongly anionic, water-soluble sulfur group, a shielded amide group, and an unsaturated double bond, which gives it excellent comprehensive properties. AMPS has good complexation, adsorption, biological activity, surface activity, hydrolysis stability, and thermal stability. It can be used for copolymerization and addition reaction, and can be widely used in various fields such as water treatment, oilfield chemistry, chemical fiber, water-absorbing materials, plastics, coatings, papermaking, textiles, printing and dyeing, biomedicine, magnetic materials, and cosmetics.

1. Water treatment: The homopolymer of AMPS monomer or the copolymer with acrylamide, acrylic acid and other monomers can be used as a sludge dehydrating agent in the sewage purification process, and as an anticorrosive agent for iron, zinc, aluminum, copper and alloys in a closed water circulation system; it can also be used as a descaling agent and scale inhibitor for heaters, cooling towers, air purifiers and gas purifiers.

2. Oilfield chemistry: The application of products in the field of oilfield chemistry is developing rapidly. The scope includes oil well cement admixtures, drilling fluid treatment agents, acidizing fluids, fracturing fluids, completion fluids and workover fluid additives.

3. Synthetic fiber: AMPS is an important monomer for improving the comprehensive properties of some synthetic fibers, especially acrylic or chloroacrylic fibers. Its dosage is 1%-4% of the fiber, which can significantly improve the fiber's whiteness, dyeability, antistatic, air permeability and flame retardancy.

4. Textile pulp: The copolymer of 2-acrylamide-2-methylpropanesulfonic acid, ethyl acetate and acrylic acid is an ideal pulp for cotton and polyester blended fabrics. It is easy to use and easy to remove with water.

5.Papermaking: The copolymer of 2-acrylamide-2-methylpropanesulfonic acid and other water-soluble monomers is an indispensable chemical for various paper mills. It can be used as a drainage aid, sizing agent, to increase the strength of paper, and can also be used as a pigment dispersant for color coating.
