Abstract
A composite material is provided by contacting a clay mineral having laminated aluminum silicate layers with an organic monomer to allow the organic monomer to be adsorbed on or intercalated between the aluminum silicate layers, and contacting the clay mineral with a silane compound having 2 to 4 chlorine atoms to promote polymerization of the organic monomer, thereby forming a composite material composed of a clay mineral having organic high polymer adsorbed thereon or intercalated therebetween. The composite material thus obtained has a strong chemical bond between inorganic clay mineral and organic high polymer.
