  • Patent number: 8372518
    Abstract: An antistatic styrenic polymer composition comprises 30 to 70 wt % of a styrenic polymer, 5 to 40 wt % of a potassium ionomer, 1 to 10 wt % of one or more polyols, and 2 to 20 wt % of an ethylene copolymer, based on the total weight of the styrenic polymer composition which has reduced dust absorption and improved mechanical performances. Also disclosed are articles made of the composition such as film or sheet including multilayer structure and items obtained by extrusion molding, coextrusion molding, injection molding, thermoform molding, compression molding or blow molding.
    Type: Grant
    Filed: December 8, 2009
    Date of Patent: February 12, 2013
    Assignee: E I du Pont de Nemours and Company
    Inventors: Karlheinz Hausmann, Christina Troeltzsch
  • Publication number: 20080132628
    Abstract: An antistatic styrenic polymer compositions comprises 30 to 70 wt % of a styrenic polymer, 5 to 40 wt % of a potassium ionomer, 1 to 10 wt % of one or more polyols, and 2 to 20 wt % of an ethylene copolymer, based on the total weight of the styrenic polymer composition which, if compared with compositions of the state of the art, shows reduced dust absorption and improved mechanical performances. Also disclosed are articles made of the composition such as film or sheet including multilayer structure and items obtained by extrusion molding, coextrusion molding, injection molding, thermoform molding, compression molding or blow molding.
    Type: Application

  • Patent number: 7265176
    Abstract: Disclosed is a composition comprising or produced from nanoparticle-sized TiO2, an ethylene copolymer or ionomer of the ethylene copolymer, and optionally a second polymer. Also disclosed are films and other shaped articles produced therefrom. The composition, possessing a UV light barrier, can be used to protect the products that may be susceptible to UV such as foodstuffs.
