Polyacrylamide CAS#9003-5-8
High Water Solubility: Polyacrylamide is a water-soluble polymer, making it easy to dissolve and apply in various aqueous systems.
Customizable Molecular Structure:Its molecular structure contains numerous amide groups, allowing for chemical modification to meet specific performance requirements.
Versatile Functionalization: By introducing carboxyl groups, quaternary ammonium groups, or other functional groups, polyacrylamide can be tailored into anionic, cationic, or nonionic forms.
Wide Application Potential: The ability to adjust its charge type and chemical properties makes polyacrylamide suitable for diverse industrial, environmental, and chemical applications.
Polyacrylamide (CAS#9003-5-8) is a water-soluble, high-molecular-weight polymer produced through the polymerization of acrylamide monomers or their copolymerization with other monomers. Its molecular structure contains numerous amide groups, and through chemical modification, additional groups such as carboxyl or quaternary ammonium can be introduced to create products with varying charge types.
