AMPS is an important monomer, has good complexion, adsorption, biological activity, surface activity, hydrolysis stability and thermal stability. Its copolymers or homopolymers with different molecular weight can be widely used in textile, oil drilling, water treatment, papermaking, dying, coating, cosmetics, electronics, etc. because of its unique formular structure-containing sulfonic acid group and unsaturated radical, thus showing excellent properties in many aspects.

Hydrolytic and thermal stability: The geminal dimethyl group and the sulfomethyl group combine to sterically hinder the amide functionality and provide both hydrolytic and thermal stabilities to AMPS-containing polymers.
Polarity and hydrophilicity: The sulfonate group gives the monomer a high degree of hydrophilicity and anionic character at wide range of pH. In addition, AMPS is absorbing water readily and also imparts enhanced water absorption and transport characteristics to polymers.
Solubility: AMPS is very soluble in water and dimethylformamide (DMF) and also shows limited solubility in most polar organic solvents.
Inhibition of divalent cation precipitation: Sulfonic acid in AMPS is a very strong ionic group and ionizes completely in aqueous solutions. In applications where the precipitation of mineral salts is undesirable, the incorporation of a polymer containing even a small quantity of AMPS can significantly inhibit the precipitation of divalent cations. The result is a significant reduction in the precipitation of a wide variety of mineral salts, including calcium, magnesium, iron, aluminum, zinc, barium and chromium.

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. Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid. Due to including carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity) in this copolymer, Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer has high calcium tolerance and good scale inhibition for calcium phosphate, calcium carbonate and zinc scale. When built with organophosphines, the synergic effect is obvious. Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer is suitable to be used in water quality of high pH and high alkaline, it is one of the ideal scale inhibitor and dispersant on high concentration index.

Personal care: Strong polar and hydrophilic properties introduced to a high molecular weight AMPS homopolymer are exploited as a very efficient lubricant characteristic for skin care.
Medical hydrogel: High water-absorbing and swelling capacity when AMPS is introduced to a hydrogel are keys to medical applications. Hydrogel with AMPS showed uniform conductivity, low electrical impedance, cohesive strength, appropriate skin adhesion, and biocompatible and capable of repeated use and have been used to electrocardiograph (ECG) electrodes, defibrillation electrode, electrosurgical grounding pads, and iontophoretic drug delivery electrodes.[21][22][23] In addition, polymers derived from AMPS are used as the absorbing hydrogel and the tackifier component of wound dressings. Is used due to its high water absorption and retention capability as a monomer in superabsorbents e.g. for baby diapers.
Oil field applications: Polymers in oil field applications have to stand hostile environments and require thermal and hydrolytic stability and the resistance to hard water containing metal ions. For example, in drilling operations where conditions of high salinity, high temperature and high pressure are present, AMPS copolymers can inhibit fluid loss and be used in oil field environments as scale inhibitors, friction reducers and water-control polymers, and in polymer flooding applications.
Water treatment applications: The cation stability of the AMPS-containing polymers are very useful for water treatment processes. Such polymers with low molecular weights cannot only inhibit calcium, magnesium, and silica scale in cooling towers and boilers, but also help corrosion control by dispersing iron oxide. When high molecular weight polymers are used, they can be used to precipitate solids in the treatment of industrial effluent stream.
Crop protection: increases in dissolved and nanoparticulate polymer formulations bioavailability of pesticides in aqueous-organic formulations.
Membranes: It increases water flow, retention and fouling resistance of asymmetric ultrafiltration and microfiltration membranes and is being studied as an anionic component in polymer fuel cell membranes.

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 .

AMPS is reactive, hydrophilic, sulfonic acid acrylic monomer used to alter the chemical properties of wide variety of anionic polymers. AMPS is a kind of vinyl monomer with sulfonic acid group, which has a good thermal stability. The decomposition temperature can be up to 210℃ and the temperature of sodium salt copolymer can reach 329℃. Its hydrolysis is very slow in aqueous solution. Sodium salt solution has good anti-hydrolysis performance with high PH value. Under acid condition, the hydrolysisresistant performance of its copolymer is better than that of polyacrylamide. The monomer can be made into crystal or sodium salt solution. AMPS is used in many areas including water treatment, oil field, construction chemicals, hydrogels for medical applications, personal care products, emulsion coatings, adhesives, and rheology modifiers.

Properties
Hydrolytic and thermal stability: The geminal dimethyl group and the sulfomethyl group combine to sterically hinder the amide functionality and provide both hydrolytic and thermal stabilities to AMPS-containing polymers.
Polarity and hydrophilicity: The sulfonate group gives the monomer a high degree of hydrophilicity and anionic character at wide range of pH. In addition, AMPS is absorbing water readily and also imparts enhanced water absorption and transport characteristics to polymers.
Solubility: AMPS is very soluble in water and dimethylformamide (DMF) and also shows limited solubility in most polar organic solvents.
Inhibition of divalent cation precipitation: Sulfonic acid in AMPS is a very strong ionic group and ionizes completely in aqueous solutions. In applications where the precipitation of mineral salts is undesirable, the incorporation of a polymer containing even a small quantity of AMPS can significantly inhibit the precipitation of divalent cations.

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.

Construction applications

Superplasticizers with AMPS are used to reduce water in concrete formulations. Benefits of these additives include improved strength, improved workability, improved durability of cement mixtures. Redispersible polymer powder, when AMPS is introduced, in cement mixtures control air pore content and prevent agglomeration of powders during the spray-drying process from the powder manufacturing and storage. Coating formulations with AMPS-containing polymers prevent calcium ions from being formed as lime on concrete surface and improve the appearance and durability of coating.

2-Acrylamido-2-methylpropane sulfonic acid (AMPS) is a reactive, hydrophilic, sulfonic acid acrylic monomer used to alter the chemical properties of wide variety of anionic polymers. In the 1970s, the earliest patents using this monomer were filed for acrylic fiber manufacturing. Today, there are over several thousands patents and publications involving use of AMPS in many areas including water treatment, oil field, construction chemicals, hydrogels for medical applications, personal care products, emulsion coatings, adhesives, and rheology modifiers.
