  • Synthesis of thermoplastic polyurethane composites
    Publication number: 20070072991
    Abstract: The present invention relates to nanocomposites and methods to produce nanocomposites. More particularly, the present invention relates to nanocomposites of thermoplastic polyurethanes that include one or more nanoparticles therein, and to methods to produce such nanocomposites. In one embodiment, the present invention relates to polyurethane nanocomposites wherein organoclay particles are tethered to the polyurethane. In one embodiment, a polymer-particle composite comprising: at least one polyurethane polymer; and particles of at least one modified and/or functionalized compound, wherein the particles of at least one modified and/or functionalized compound contain at least one site that will react with one or more isocyanate groups contained in the polyurethane polymer, and wherein the particles of at least one modified and/or functionalized compound become tethered to one or more isocyanate groups of the polyurethane polymer thereby yielding the polymer-particle composite.
