The rheological behavior of PA11/POE/OMMT nanocomposites was studied by using XLY-Ⅱ rheometer. The curves of lgτω~lg, lgηa!lg, lgηa!1/T were obtained. The experimental results showed that PA11/POE/OMMT nanocomposites were pseudoplastic fluid. The apparent viscosity of the blends reduced with the increase of the shearing stress.Compared with PA11/POE blends, the addition of OMMT increased the apparent viscosity. The viscous activation energy of PA11/POE/OMMT blends declined as the increase of shearing stress, which indicated that the PA11/POE/OMMT blends could be processed over a wide temperature at a high shearing stress.
