Products Description of 2-Acrylamide-2-methylpropanesulfonic acid CAS#15214-89-8
2-Acrylamido-2-methylpropanesulfonic acid (AMPS) is a water-soluble sulfonic acid group with strong anionic properties, which makes it salt-resistant, high-temperature-resistant, dye-affinity, conductive, ion-exchangeable and highly tolerant to divalent cations; the amide group makes it have good hydrolysis stability, acid and alkali resistance and thermal stability; and the active double bond makes it have addition polymerization properties, and it can produce copolymers with a variety of hydrocarbon monomers.

Product Application of 2-Acrylamide-2-methylpropanesulfonic acid CAS#15214-89-8
The product has polymerizable vinyl and hydrophilic sulfonic acid groups in the molecule, and can be copolymerized with water-soluble monomers such as acrylonitrile and acrylamide, and non-water-soluble monomers such as styrene and vinyl chloride. The hydrophilic sulfonic acid group is introduced into the polymer to make the fibers, films, etc. hygroscopic, water-permeable and conductive.
It can be used in the papermaking industry and wastewater treatment. It can be used as a coating modifier, fiber modifier and medical polymer. 2-Acrylamide-2-methylpropanesulfonic acid can be homopolymerized or copolymerized. The average heat of polymerization of 2-acrylamide-2-methylpropanesulfonic acid in water is 22 kcal/coulamide, which can be used as a polymerization medium.
Generally, water-soluble ammonium persulfate, hydrogen peroxide, etc. are used as initiators. Commonly used monomers with 2-acrylamide-2-methylpropanesulfonic acid are acrylonitrile, acrylic acid, acrylamide, styrene, ethyl acetate, etc.
It is a homopolymer and copolymer monomer, widely used in oil fields, textiles, papermaking, water treatment, synthetic fibers, printing and dyeing, plastics, water-absorbent coatings, biomedicine, etc.
