The crystallization behavior and structure of polyamide 6 (PA6) nanocomposites containing 3 wt.‐% montmorillonite (MMT) were investigated for different cooling conditions using differential scanning calorimetry and X‐ray diffraction. In sharp contrast to PA6 and other semicrystalline polymers, increased cooling rates resulted in higher crystallinity of PA6/MMT. The highest crystallinity (60.8%) occurred in the liquid nitrogen‐quenched PA6/MMT film. The results show that the γ ‐crystalline form is dominant in the rapidly cooled PA6/MMT.
