  • Compositions of polyesters and fibrous clays
    Patent number: 9040615
    Abstract: Compositions of thermoplastic polyesters containing dispersed nanoparticles of fibrous clay are made by polymerizing the polyester precursors in the presence of exfoliated fibrous clay that has not been organically modified. The compositions have good physical properties and can be melt molded into various articles. Many of these articles may be coated (painted) and are especially useful for appearance parts such as visible exterior automotive body parts.
    Type: Grant
    Filed: November 14, 2011
    Date of Patent: May 26, 2015
    Assignee: E I DU PONT DE NEMOURS AND COMPANY
    Inventors: David T. Williamson, Thomas M. Herrod, William M. Simmons, Henry Max Schleinitz

  • FACILATATED DISPERSION OF NANOFILLERS FOR THE PREPARATION OF NANOCOMPOSITES
    Publication number: 20090192254
    Abstract: Compositions of thermoplastic polyesters and sepiolite-type clay in which the clay is dispersed in the polyester as often fibrous particles whose smallest dimension is less than 100 nm are made by polymerizing the polyester precursors in the presence of the clay. The compositions have good physical properties and can be melt molded into various articles. Many of these articles may be coated (painted) and are especially useful for appearance parts such as visible exterior automotive body parts.
