Résumé	Six compositions containing commercial polypropylene, PP, and monodispersed, untreated phlogopite mica were prepared. Their rheological properties were determined at 180°C in dynamic and capillary flows. The results are discussed in terms of strain‐induced orientation of mica flakes. Two critical volume fractions were found to affect the flow: Φc defined as a concentration of flakes overlap and Φm as a concentration of maximum packing of freely sedimenting particles. At Φ > Φc yield stress and at Φ > Φm non‐linearity in dynamic response were observed.
