Abstract: A method for producing a nanocomposite polymer that includes the step of adding an olefin to a metallocene polymerization catalyst treated dispersion of an acid treated cation exchanging layered silicate material in a solvent so that the olefin polymerizes to form the nanocomposite polymer. An exfoliated acid treated cation exchanging layered silicate material dispersed in a polymer matrix, wherein more than about fifty percent of the acid treated cation exchanging layered silicate material is found by electron microscopy to have five or fewer layers. A metallocene polymerization catalyst treated, acid treated cation exchanging layered silicate material.

Abstract: The present invention is a nanocomposite which is a dispersion of nanofiller particles derived from layered metal oxides or metal oxide salts. The nanocomposite is advantageously prepared by first swelling an untreated clay in water, then removing the water to form an organophilic clay that is dispersible in non-polar organic solvents. The organophilic clay can then be treated with an alkyl aluminoxane and subsequently a catalyst to form a complex that promotes olefin or styrenic polymerization and platelet dispersion. The nanocomposite can be prepared directly by in situ polymerization of the olefin or the styrene at the nanofiller particles without shear, without an ion exchange step, and without the need to incorporate polar substituents into the polyolefin or polystyrene.
