Abstract
Provided herein is a process for producing a composite material composed of a polymer and the layered silicate constituting the clay mineral being connected to the polymer through ionic bonding. The process comprises contacting a layered clay mineral with a swelling agent in the presence of a dispersion medium, thereby forming a complex, mixing said complex containing said dispersion medium with a monomer, and polymerizing said monomer contained in said mixture. The process permits the economical and efficient production of a composite material in which the layered silicate is uniformly dispersed.
