Specialty Polymer

AMPS monomer is a highly reactive, hydrophilic, sulphonic acid acrylic monomer capable of imparting a number of distinctive, high performance characteristics to a wide variety of ion-containing polymers and reaction products. Due to its high level of purity and reactivity, the incorporation of small quantities of AMPS monomer during polymerization enables processors in diverse applications to formulate products with enhanced:

  • Hydrolystic stability

  • Inhibition of divalent cation precipitation

  • Thermal stability

  • Mechanical shear stability

  • Resistance to hydrolysis

  • Ionic character

  • Rheology control

  • Solubility

  • Lubricity

Unlike other commercially available sulphonic acid monomers, AMPS monomer’s exceptionally higher level of purity ensures consistent, predictable performance. AMPS is available as a free-flowing, low-dusting granular solid or as an aqueous sodium salt solution. Its acrylamide structure minimizes chain transfer and permits both high and low molecular weight polymer generation for optimum versatility.

Properties of AMPS:

  • Hydrolytic and thermal stability: The geminal dimethyl group and the sulphomethyl group combine to sterically hinder the amide functionality and provide both hydrolytic and thermal stabilities to AMPS containing polymers.
  • Polarity and Hydrophilicity: the sulphonate 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 polymer.
  • 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: Sulphonic acid in AMPS is a very strong ionic groups 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 significant reduction in the precipitation of a wide variety of mineral salts, including calcium, magnesium, iron, aluminum, zinc, barium and chromium.

Applications:

  • Oil field: 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. In drilling operation, 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: The cation stability of the AMPS containing polymers are very useful for water treatment processes. Such polymers with low molecular weights can not only inhibit calcium, magnesium, and silica scale in cooling towers and boilers, but also helps corrosion control by dispersing iron oxide
  • Medical Hydrogel: High water absorbing and swelling capacity when AMPS is introduced to a hydrogel are keys to medical applications. Hydrogel with AMPS appropriate skin adhesion, and biocompatible and capable of repeated use and have been use to electrocardiograph (ECG) electrodes, defibrillation electrode. In addition, polymer delivers derived from AMPS are used as the absorbing hydrogel and the tackifier component of wound dressing. Is used due to its high water absorption and retention capability as a monomer in superabsorbents e.g for baby diapers.
  • 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.
  • Coating : Its sulfonic acid group gives the monomers ionic character over a wide range of PH. Anionic charges from AMPS fixed on polymer particles enhance the chemical and shear stabilities of polymer emulsion and also reduce the amount of surfactant leaching out of paint film.
  • Adhesives: It improves the thermal and mechanical properties of adhesives, and increases the adhesives, and increases the adhesive strength of pressure sensitive adhesive formulations and makes wood glue to improve adhesive strength and mechanical properties with great rheology.
  • Detergent: AMPS is used to enhance the washing performance of surfactant by binding multivalent cations and reducing dirt attachment.
  • Acrylic Fibers: A number of enhanced performance characteristics are imparted to acrylic, modified acrylic, polypropylene and polyvinylidene fluoride fibers because it improves dye receptivity, promote rich colors, more compact fiber structure, tensile strength, static resistance, provides salt resistance, enhance mechanical and thermal stability, and increases process cleanliness and efficiency.
  • Construction: Superplasticizers with AMPS are used to reduce water in concrete formulations. Benefits of these additives include improved strength, workability, durability of cement mixture. 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.
