Procedure

Thirty grams of a commercially available montmorillonite powder was dispersed in one liter of water by a mixer to prepare a montmorillonite suspension. After 20 g of ε-caprolactam was added to this suspension, 50 cc of dichlorodimethylsilane was further added, thus forming an intercalated compound of montmorillonite, ε-caprolactam and silanol. The formation of the intercalated compound was confirmed through X-ray diffraction, infrared absorption spectrum and differential thermal analysis, or the like. X-ray diffraction and infrared absorption spectra confirmed that this intercalated compound was formed into an intercalated compound composed of montmorillonite and nylon 6 when it was heated at about 200° C. for one hour in air to effect polymerization of ε-caprolactam between the layers.
