Polymerization of glycinamide‐conjugated monomer alone in concentrated aqueous solution enables facile formation of a mechanically strong and a highly stable supramolecular polymer (SP) hydrogel because of the cooperatively hydrogen‐bonded crosslinking and strengthening effect from dual amide motifs. This SP hydrogel exhibits thermoplastic processability, injectability, and self‐reparability because of the dynamic destruction and reconstruction of hydrogen bonds in response to temperature change.
