Popis:	Addition of minute amounts of Congo Red (a benzidine derivative) to polymer additives of polyethylene oxide greatly affect the turbulent drag reduction characteristics of the polymer. A dipole type cross coupling mechanism is suggested which could possibly explain the flow behavior of these dilute additive solutions in drag reduction.
