Polymerization reaction of εA-caprolactam initiated at an interlayer spacing of smectite and the structure of the obtained intercalated compounds were reviewed. Characteristics of clay minerals as a host for intercalation or inclusion; functions of interlayer cations, swelling behaviour, layer charge distribution, two dimentional character of silicate layers, and reactions at crystal edges of layers, were discussed.
