Which category does sodium polyacrylate belong to

Sodium polyacrylate belongs to the acrylic acid polymer category. Acrylic polymers are a type of polymer compound obtained through polymerization reaction with acrylic acid and its derivatives as the main monomers. Based on the specific structure and properties of polymers, acrylic polymers can be further classified into different types, such as the following common classifications:

Polyacrylic Acid SodiumPAAS: A polymer formed by polymerization of acrylic monomers, which neutralizes some carboxyl groups of acrylic acid to obtain a sodium salt form. Sodium polyacrylate has excellent water absorption, dispersibility, and adhesion, and is commonly used in water treatment, textile processing, papermaking, pharmaceuticals, and other fields.

Polyacrylonitrile (PAN) is a polymer formed by polymerization of vinyl formate (also known as acrylonitrile) as a monomer. It has high strength, wear resistance, and tensile resistance, and is commonly used in textiles, synthetic fibers, and carbon fibers.

Poly (methyl methacrylate) (PMMA) is a polymer formed by polymerization of methyl methacrylate as a monomer. It has properties such as transparency, good weather resistance, and UV resistance, and is commonly used in the production of plastic glass, optical devices, decorative materials, etc.

Polypropylene Acid: A polymer formed by polymerization of acrylic monomers, with high temperature stability, corrosion resistance, and electrical insulation properties. It is commonly used in electronic devices, chemical engineering, and other fields.

The above are some common types of acrylic polymers, and different acrylic polymers have differences in chemical structure and properties, thus having specific functions and applications in different application fields.
