The onset of flow instabilities (encountered during extrusion of polymer melts) corresponds to the flow conditions when the critical shear stresses or the critical shear rates are attained. These critical values were experimentally determined for two cases of polymer blends. Consequently there were used the mixture rules of a logarithmic type for desciption of behaviour of critical shear values.
