Description Of 2-Acrylamido-2-Methylpropane Sulfonic Acid/AMPS(CAS 15214-89-8)

2-Acrylamido-2-Methylpropane Sulfonic Acid is a unique vinyl monomer with a sulfonic acid group. It is a versatile monomer possessing thermal stability, a hydrolytic nature, hydrophilicity, polarity, and reactivity ratio, and it can be both copolymerized and homopolymerized.

AMPS monomer is a highly reactive, hydrophilic, sulphonic acid acrylic monomer used to alter the chemical properties of a large variety of anionic polymers. The aqueous solution of this compound is acidic in nature and soluble in water but insoluble in acetone.

ATBS monomer along with sodium salt allows the polymers to manufacture high-quality polymers for application in a wide range of consumer and industrial products. The AMPS monomer is organic, available in both granules and liquid form.

Applications Of 2-Acrylamido-2-Methylpropane Sulfonic Acid/AMPS(CAS 15214-89-8)

AMPS is widely used in textiles (spinning, dyeing), plastics, papermaking, coatings, sewage treatment, oil extraction and other industrial production, manufacturing excellent antistatic agents, dyeing agents, dispersants, water absorbing agents, flocculants, Foam stabilizers, special coating, oil field chemical agent, etc.

Water Treatment Field

One of the main uses of AMPS is to produce water treatment agents. At present, the research and production of this product in water treatment agents have been widely carried out in China, especially the research on organic phosphonic acid and carboxylic acid copolymer, which is the most widely used water treatment agent in industrial cooling water system. At present, the application of AMPS in water treatment agents accounts for 1/3 of the world's output. In recent years, as countries in the world pay more and more attention to environmental protection, the treatment of various wastewater has also become particularly important. It is believed that the market demand for this product will increase year by year.

Textile And Dye Industry

AMPS is an important monomer to improve the overall performance of some synthetic fibers, especially acrylic or acrylic fiber. Its dosage is 1% to 4% of the fiber, which can significantly improve the whiteness, dyeability, antistatic, and antistatic properties of the fiber. Breathability and flame retardancy. The modified acrylic fiber can be dyed in various colors, can increase the moisture absorption rate, make the acrylic cellulose closer to natural wool, can improve the spinning process, increase the spinnability, and enhance the luster, color and water absorption of acrylic products, Flexibility is also greatly improved. It is precise because of these advantages that the monomer has been widely used in many acrylic fiber factories in the United States, Britain, Italy, and India.

Oil Industry

Water-soluble polymers have important uses in the petroleum industry. They are widely used in many operations such as drilling, cementing, well completion and workover, and enhanced oil recovery (EOR). AMPS has a wide range of applications in the field of oilfield chemistry, covering the scope of drilling fluid treatment agents, oil well cement additives, acidulants, fracturing agents, completion fluids and workover fluid additives, water shutoff agents, tertiary oil recovery and flooding Agent, dispersant, oily sewage treatment agent, etc.

The most common is the binary, ternary and multi-component water-soluble copolymers formed by AMPS and monomers such as acrylamide, acrylic acid, acrylonitrile, N-ethylpyrrolidone, and N,N-dimethylacrylamide. The terpolymer made of AMPS, methacrylic acid and acrylamide is used as cement admixture, which can play a good high-temperature retarding effect; the copolymer with N,N-dimethylacrylamide can be used as Oil well cement slurry fluid loss agent; the graft copolymer of AMPS, calcium lignosulfonate and acrylamide is a better cement slurry distribution agent or early strength agent, enhancer, etc.; AMPS and acrylic acid, tetrahydrobenzoic acid, wood Graft copolymers of sulfonic acid, etc. can be used to prepare drilling fluid dispersants and stabilizers with good calcium resistance, viscosity reducers, fluid loss additives, etc. In addition, the block copolymer of AMPS and N-vinylpyrrolidone can be used as a thickener for tertiary oil recovery. It will not be degraded under high temperature, high pressure and high shear conditions, and has good stability.

Paint Industry

AMPS is used in the coating industry as a performance enhancer for coating modifiers, adhesives and finishing agents with excellent performance. Adding AMPS to acrylic cathodic electrophoretic coatings and water-soluble thermal curing coatings can promote the crosslinking and curing of the coating film during drying, so as to obtain a coating film with good gloss and other properties.
