  • Composite polymer clay material and process for producing the same
    Patent number: 6734229
    Abstract: A process for producing a composite material comprising a polymer with polar or polarizable groups, a layered silicate dispersed therein, and a substance such as surfactant which controls the crystalline structure or molecular conformation of the polymer. The process produces the composite material without in situ formation or melting. The composite material has an increased glass transition temperature, improved mechanical strength and high optical clarity or transparency.
