A novel association of poly(acrylic acid) in dilute solution is induced by high shear flow, producing a rigid chain morphology via interchain H‐bonding; the association is destroyed upon adding salt to the shearing solution. Such macromolecular changes in conformation are reflected in drag reduction changes as a result of flow‐polymer interaction.
