Abstract The micelle‐forming monomers of sodium 6‐acrylamidocaproate (Na 6‐AAC), sodium 11‐acrylamidoundecanoate (Na 11‐AAU), sodium 11‐( N ‐methylacrylamido) undecanoate (Na 11‐MAAU), and sodium 11‐( N ‐ethylacrylamido) undecanoate (Na 11‐EAAU) have been synthesized and polymerized. Except poly(Na 6‐AAC), the molecular weights of the other three poly(sodium acrylamidoalkanoate) s were over 10 6 . They behave as strong anionic polyelectrolytes in aqueous solutions. Their solution properties, such as viscosity, charge density, and radius of gyration, were investigated. The performance of these anionic polyelectrolytes as coagulant aids in water treatment were assessed by jar test. Poly(Na 6‐AAC) and poly (Na 11‐AAU) were superior to poly (Na 11‐MAAU) and poly (Na 11‐EAAU) in terms of flocs settling. All these four anionic polyelectrolytes tested in water treatment are as effective as a commercially available cationic polyamine organic coagulant (Hyperfloc CP 753).
