Polyacrylamide(PAM), has a mf:(C₃H₅NO)_x , mw: 71.08. It is typically a high molecular weight polymer formed by end-to-end bonding of acrylamide monomers. Its molecular chain contains amide groups (-CONH₂), enabling reactions such as hydrolysis and cross-linking. It exhibits excellent thermal stability. Cationic polyacrylamide carries a positive charge, while anionic polyacrylamide carries a negative charge, enabling adsorption or flocculation with substances of opposite charge.

Water Treatment: It serves as a flocculant for treating industrial wastewater, domestic sewage, and drinking water, rapidly settling suspended particles to reduce turbidity and COD.
Oil Production: PAM functions as a flooding agent and drilling fluid additive, enhancing oil recovery rates while improving drilling fluid viscosity and stability.
Paper Industry: As retention aids, filtration aids, and strength enhancers, polyacrylamide improves pulp fiber utilization while enhancing paper strength and drainage properties.
Other Applications: Used as thickening agents in food processing, sizing agents in textiles, water retention agents for soil improvement, and separation/purification aids in pharmaceuticals, mining, and other industries.
