  • Process for stabilizing mixtures based on halogenated polymers
    Patent number: 5166241
    Abstract: Thiol compounds are combined with an organometallic halide or metallic halide to provide thermal stability to vinyl halide polymers.
    Type: Grant
    Filed: November 22, 1989
    Date of Patent: November 24, 1992
    Inventor: Simon Kornbaum
  • Sterilization of objects made of halogeno-vinylic polymers using ionizing radiation
    Patent number: 4616046
    Abstract: A process for the sterilization of objects made of polymers in which the molecule contains a halogen, or of products packaged in such polymer material, the polymer containing a heat stabilizer wherein, prior to irradiation of the object or the package and its contents, there is incorporated into the polymer one or more esters carrying at least one mercaptan function in the proportion of one --SH group for 3 to 10 carbon atoms.
    Type: Grant
    Filed: May 7, 1984
    Date of Patent: October 7, 1986
    Assignee: Ato Chimie
    Inventors: Simon Kornbaum, Jean-Yves Chenard
  • Process for rendering polymers resistant to ionizing radiation, and compositions obtained thereby
    Patent number: 4412897
    Abstract: The process concerns stabilization of polymers against ionizing radiation where the polymer molecule contains a halogen. It comprises incorporating hydroquinone into the polymer, especially into polyvinyl chloride, the polymer containing both a metallic compound, heat stabilizer, and also a mercaptan.
    Type: Grant
    Filed: October 9, 1981
    Date of Patent: November 1, 1983
    Assignee: Ato Chimie
    Inventors: Simon Kornbaum, Jean-Yves Chenard
  • Process for manufacturing thermoplastic compositions and containers made of such compositions
    Patent number: 4309465
    Abstract: A process for manufacturing thermoplastic materials having an elevated gas impermeability and/or improved physical properties. This process is characterized in that it comprises mixing at least partially imcompatible polymers, gelling them by the combined action of heat, pressure and kneading. The gelled mixture is then subjected to laminar flow through substantially parallel surfaces in which the ratio of the length of the surfaces to the distance between them is greater than 10.A thermoplastic material having increased gas impermeability as well as containers made out of said materials.A packaging method in which the thermoplastic materials of the invention are used to package oxygen sensitive materials.
    Type: Grant
    Filed: October 21, 1977
    Date of Patent: January 5, 1982
    Assignee: Ato Chimie
    Inventor: Simon Kornbaum
