What is polyacrylamide

In industry, polyacrylamide generally refers to a polymer containing more than 50% acrylamide (AM) monomer, which is a linear water-soluble polymer.

The main chain of the polyacrylamide molecule has a large number of chemically active amide groups. This amide group can react with a variety of compounds to form a variety of polyacrylamide derivatives, and can also form a variety of compounds that can form hydrogen bonds. Strong hydrogen bond. This gives polyacrylamide a variety of properties, such as surface activity, viscosity increasing, flocculation, etc., so it has a wider range of applications.

Polyacrylamide is a water-soluble polymer (compound). Polyacrylamide (PAM) is a collective term for acrylamide homopolymer or polymer copolymerized with other monomers. It is the most widely used water-soluble polymer. One of the varieties.

Polyacrylamide series products can be divided into non-ionic (NPAM), cationic (CPAM) and anionic (CPAM). These polymers can be homopolymers or copolymers.

Polyacrylamide is widely used in industries such as petroleum exploration, papermaking, water treatment, textiles, mineral processing, and agriculture. According to statistics, about 37% of the global polyacrylamide production is used in wastewater treatment, 27% in the petroleum industry, and 18% in the paper industry.

Industrial polyacrylamide and its derivatives are produced by acrylamide radical polymerization. The polymerization method is divided into bulk polymerization, solution polymerization, suspension polymerization and emulsion polymerization according to the dispersion state of monomers in the medium. According to the dissolution state of monomer and polymer, it can be divided into homogeneous polymerization and heterogeneous polymerization. Polyacrylamide products have three dosage forms: aqueous colloid, powder and emulsion.

In recent years, with the development of modern science and technology, the varieties of polyacrylamide and its derivatives have been increasing, and the application fields have become more and more extensive. The new synthetic technology of polyacrylamide has continuously expanded the scale of industrial production.
