The interaction of polyamide 6 (PA) with clay is studied via rheological approaches. The relationship of the effective viscosity (η r ), the clay volume fraction (ϕ clay ), the aspect ratio ( P ), and the critical volume fraction (ϕ c ) is built up by using the Maron‐Pierce model. The time–temperature superposition (TTS) is applied to evaluate the relaxation of PA in the presence of clay under various temperatures. Furthermore, the modified Cox‐Merz rule is used to build up the viscosity response of PA/clay nanocomposites under both dynamic shear and steady shear. © 2011 Wiley Periodicals, Inc.
