Polyacrylamide, often abbreviated as PAM, is a synthetic polymer formed from acrylamide monomers. It exists in various forms, including anionic, cationic, and non-ionic, depending on the presence and type of charged groups incorporated into its structure. These different forms give polyacrylamide a wide range of properties and applications.

In its solid form, polyacrylamide is typically a white, granular powder. When dissolved in water, it forms viscous solutions or gels. The degree of polymerization and the presence of ionic charges significantly influence the viscosity and gel-forming capabilities of PAM. This property makes it useful as a thickener, flocculant, and binder.

Polyacrylamide finds extensive use in water treatment, where its flocculating properties are employed to aggregate suspended particles, facilitating their removal from water. It is also utilized in enhanced oil recovery to increase the viscosity of injected water, improving sweep efficiency. In agriculture, it can be used as a soil conditioner to improve water retention and reduce erosion. Furthermore, polyacrylamide is a key component in the production of gels for electrophoresis, a common laboratory technique for separating biomolecules. Its versatility stems from its ability to be chemically modified to suit specific industrial and scientific needs.
