2. Chemical Properties

-AMPS molecules contain strong anionic sulfonic acid groups, which give them excellent salt resistance, high temperature resistance, dyeing affinity, conductivity, ion exchange and good tolerance to divalent cations.

-Amide groups give them good hydrolysis stability, acid and alkali resistance and thermal stability.

-Active carbon-carbon double bonds give them addition polymerization properties and can form copolymers with a variety of hydrocarbon monomers.

AMPS Product Parameters：

AMPS Application:

AMPS is widely used in many fields as a homopolymer and copolymer monomer:

1. Oilfield Chemistry:

* Used to prepare oilfield chemicals, such as drilling fluid, completion fluid and fracturing fluid.

* As a modified monomer, it improves the salt resistance, high temperature resistance and shear resistance of oil production polymers.

2. Water Treatment:

* Its homopolymer or copolymer with monomers such as acrylamide and acrylic acid can be used as a sludge dehydrating agent in the sewage purification process.

* Used as a preservative for iron, zinc, aluminum, copper and alloys in a closed water circulation system.

* It can also be used as a descaling agent and scale inhibitor for heaters, cooling towers, air purifiers and gas purifiers.

3. Synthetic Fiber Industry:

* Copolymerized with acrylonitrile to significantly improve the dyeing function of acrylic and acrylic synthetic fibers.

* Improve the hygroscopicity, heat resistance and antifouling properties of synthetic fibers, and give them ion exchange properties.

* It also has a significant improvement in dyeing effects on polyester, polyamide, polypropylene, polyvinylidene, etc.

4. Papermaking Industry:

* Water-soluble polymers containing AMPS can be used as paper reinforcing agents, agents to improve the utilization of refined pulp and its fillers.

* In the papermaking process of non-woven fabrics such as paper, it can be used as a pulp dispersant, paper peeling agent, etc.

5. Coatings Industry:

* As a performance improver such as a modifier, adhesive and finishing agent with excellent performance in the coatings industry.

* AMPS copolymers are used as the base resin of acrylic anionic electrophoretic paint or curing paint, which can significantly improve the gloss, strength and weather resistance of the coating film.
