Summary: Nylon‐6/Na + ‐montmorillonite (MMT) nanocomposites (NNNs) are synthesized by a hydrolyzed ring‐opening polymerization. At a loading of only 2 wt.‐% MMT, the tensile modulus, the flexural modulus, and the heat distortion temperature of the NNNs exhibit increases of nearly 20%, 60%, and 63 °C, respectively. Compared with that of neat nylon‐6, the temperature of the main α ‐relaxation ( T α ) of the NNNs is shifted 3.6 °C toward higher temperatures and two β ‐relaxation peaks are observed. Another interesting phenomenon is that there is a new melting peak (at about 206 °C) for the NNNs.DSC second heating curves of neat nylon‐6 (N6), nylon‐6/Na + ‐MMT nanocomposites with highly swollen Na + ‐MMT (NHM), and nylon‐6/Na + ‐MMT nanocomposites with slightly swollen Na + ‐MMT (NSM) with various amounts of Na + ‐MMT.
