Abstract
The critical overlapping concentration c' which separates the dilute and ex tremely dilute regimes for polyacrylonitrile in dimethylformamide was studi ed by viscometry. A scaling law between the reduced viscosity eta(sp)/c and the concentration for the extremely dilute regime was found and the deviat ion from the Huggins dependence was discussed.
