Performance and Application

AMPS can be used for copolymerization or homopolymerization, and is widely used in various fields such as oil field chemistry, water treatment, synthetic fibers, printing and dyeing, plastics, papermaking, absorbent coatings, biomedicine, magnetic materials, and cosmetics.

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

2. Synthetic fibers: AMPS is an important monomer that improves the comprehensive properties of some synthetic fibers, especially acrylic or acrylic fibers. Its dosage is 1%-4% of the fiber, which can significantly improve the whiteness and dyeability of the fiber. , antistatic, breathable and flame retardant.

3. Textile sizing: AMPS, a copolymer of ethyl acetate and acrylic acid, is an ideal sizing for cotton and polyester blended fabrics. It is easy to use and easy to remove with water.

4. Papermaking: The copolymer of AMPS and other water-soluble monomers can be used as a drainage aid and sizing agent to increase the strength of paper, and can also be used as a pigment dispersant for color coatings.
