What is an amps copolymer

"Amps copolymer" likely refers to a copolymer derived from the acronym "AMPS," which stands for 2-acrylamido-2-methylpropane sulfonic acid. AMPS is a zwitterionic monomer that contains both a cationic and an anionic functional group within the same molecule. When AMPS is copolymerized with other monomers, it forms a copolymer with unique properties that can be tailored based on the composition and the other monomers used.

Here are some key points about AMPS copolymers:


  • Zwitterionic Character: AMPS copolymers have both positive and negative charges within the same molecule, which can provide unique interactions with other substances.

  • Water Solubility: Due to the presence of the sulfonic acid group, AMPS copolymers are highly water-soluble.

  • Salt Tolerance: They exhibit good tolerance to salts, which can be important in various industrial applications.


  1. Flocculants: Used in water treatment processes as flocculants to aggregate fine particles and facilitate their removal.

  2. Coagulants: In similar applications, they can act as coagulants to help remove impurities from water.

  3. Dispersants: They can be used as dispersants in the paint and coatings industry to prevent the aggregation of pigments.

  4. Personal Care: In personal care products, they can be used to provide viscosity and other rheological properties.


AMPS copolymers are typically synthesized through free radical copolymerization, where AMPS is mixed with other monomers in the presence of a radical initiator.

Safety and Handling

  • Chemical Compatibility: AMPS copolymers should be stored and used in a manner that is compatible with other chemicals to avoid unwanted reactions.

  • Environmental Impact: As with any chemical used in industrial applications, care should be taken to minimize environmental impact.


  • Conditions: AMPS copolymers should be stored in a dry, cool place, away from heat and strong oxidizing agents.

The versatility of AMPS copolymers, with their unique zwitterionic properties, makes them valuable in a range of applications, particularly in the water treatment and coatings industries. The specific properties and applications of an AMPS copolymer can vary widely depending on the other monomers that are copolymerized with AMPS.
