Polyacrylamide is a synthetic polymer formed by the polymerization of acrylamide monomers, commonly available as a water-soluble homopolymer or in cross-linked gel forms. It is widely used in water treatment, enhanced oil recovery, soil conditioning, and biomedical applications where its high absorbency, rheological control, and biocompatibility are valued. Engineers select polyacrylamide over alternatives when high elongation, customizable cross-linking density, and solubility in aqueous systems are required; it is also employed in electrophoresis gels and as a drag-reducing additive in pipeline transport.
