摘要：

It was found that montmorillonite was intercalated with epsilon-caprolactam. X-ray diffraction revealed that the chain axes of the epsilon-caprolactam were parallel to the montmorillonite plates. The intercalated montmorillonite was swollen by molten epsilon-caprolactam at 200-degrees-C. Epsilon-caprolactam and 6-aminocaproic acid (accelerator) were polymerized with the intercalated montmorillonite at 260-degrees-C for 6 h, yielding a nylon 6-clay hybrid. X-ray diffraction and transmission electron micrography revealed that the silicate layers of the hybrid were uniformly dispersed in the nylon 6 matrix. Mechanical properties of the hybrid were improved. The strength and the modulus of the hybrid increased compared with the previously reported nylon 6 clay-hybrid (NCH) synthesized by montmorillonite intercalated with 12-amino-lauric acid. The heat distortion temperature (HDT) of the hybrid was 164-degrees-C, which was 12-degrees-C higher than that of NCH.
