Abstract: The present invention relates to the use of surface-modified nanoparticles to alter the morphology and microstructure of polymer blends. The addition of surface modified nanoparticles to polymer blends comprised of immiscible polymers facilitates the uniform distribution of the dispersed phase of the polymer blend. In an embodiment, the present invention relates to a polymer blend comprising (1) a continuous phase comprising at least one polymer, monomer or oligomer, and a plurality of surface-modified nanoparticles, having a particle diameter of less than about 100 nanometers, distributed in the continuous polymer phase; and (2) a dispersed phase comprising at least one polymer, monomer or oligomer, wherein the continuous polymer phase and the dispersed polymer phase are immiscible.

Abstract: This invention relates to glass microsphere (bead) coated articles having an upper surface comprising a layer of low refractive index transparent glass microspheres such as those made from recycled ordinary glass. The articles of the invention have an extremely smooth tactile feel and a low friction surface even though they can be prepared from glass microspheres intermixed with abrasive irregularly shaped glass particles. The invention also relates to the method making the bead coated articles of the invention and transfer articles that can be used to make the bead coated articles of the invention.

Abstract: Coating compositions containing identifier particles are disclosed for the retrospective identification of articles. The compositions comprise a clear lacquer binder, visually-readable microparticles and reflective spotting particles. The reflective spotting particles facilitate location of the coating on the surface of the tagged article.
