Composites were synthesized by anionic in situ polymerisation of ɛ-caprolactam in the presence of 0.1–5.0% of multiwall carbon nanotubes. It is found that nanotube filling increases rigidity and improves the friction characteristics of polycaproamide. The friction coefficient decrease is especially significant at a nanotube concentration of 0.1%. It is shown that nanotubes affect the composite film microstructure.
