摘要：

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