Buy 2-Acrylamido-2-methylpropanesulfonic acid-acrylic acid copolymer AA/AMPS CAS 40623-75-4, a chemical intermediate for AA/AMPS from TNJ Chemical, China leading 2-Acrylamido-2-methylpropanesulfonic acid-acrylic acid copolymer AA/AMPS suppliers, factory & manufacturers. If you want to buy AA/AMPS or buy AMPS, please mail to [email protected]

AA/AMPS CAS 40623-75-4 is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS). Due to including carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity) in this copolymer, AA/AMPS 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. AA/AMPS 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.

1. Water treatment:  The AMPS monomer homopolymer with the acrylamide acrylic acid monomer homopolymer, they could besludge dehydrating agent in the sewage purification process

2. Oilfield chemistry: This product is rapid development in the application of the oil field chemistry. 

3. Synthetic fiber: The AMPS is the important monomer which could change the combination property of some synthetic fiber, in particular, the orion and the modacrylic fiber  with chloride, the dosage is the 1-4 of the fiber 

4. The sizes of the textile: The copolymer of the acrylami-2-methylpropane sulfonic acid, ethyl acetate and acrylic acid, it is the ideal size of the cotton and the polyester blend fabric, it has the characteristic of easy to use and east to use the water to remove.
