The oxopolysaccharides produced by microorganisms often have non‐Newtonian flow behavior (pseudoplastic rheological behavior) which can usually be described by the so‐called power‐law. The authors present a method to check rheological data given as pairs (K, m) as far as consistency of the data sets is concerned. The results from the polymers PAA and NATROSOL are presented and compared with the literature values.
