[0002] Polyacrylamide (PAM) is a linear polymer. Polyacrylamide is a water-soluble linear polymer formed by free radical-initiated polymerization of acrylamide (AM) monomers. It has good flocculation properties and can reduce frictional resistance between liquids. It is one of the most widely used water-soluble polymers. Polyacrylamide is a hard glassy solid at room temperature. The product is in the form of glue, latex, white powder, translucent beads and flakes. It can be dissolved in water in any proportion. The aqueous solution is a uniform transparent liquid. After long-term storage, the solution viscosity may decrease due to polymer degradation. Polyacrylamide has good thermal stability and chemical stability.
