  • Thermoplastic composition comprising a copolymer based on ethylene and maleic anhydride, and industrial articles obtained from such a composition
    Patent number: 5593764
    Abstract: A thermoplastic composition comprising an uncrosslinked blend of (A) from 1 to 80 weight percent of at least one partially crystalline polymer or copolymer of ethylene, having a density lying between 0.870 and 0.945, and (B) from 20 to 99 weight percent of at least one hydrophobic, non-elastomeric, random or graft copolymer.
    Type: Grant
    Filed: March 17, 1993
    Date of Patent: January 14, 1997
    Assignee: Societe Chimique des Charbonnages S.A.
    Inventors: Lionel Guerdoux, Marius Hert
  • Multi-phase thermoplastic compositions and articles obtained therefrom
    Patent number: 5070145
    Abstract: Compositions comprising from 50 to 95% by weight of at least one polyamide resin, and from 5 to 50% by weight % of a polymer composition comprising from 84 to 99.1 mole % of units derived from ethylene and from 0.9 to 16 mole % of units derived from an unsaturated anhydride of a dicarboxylic acid and optionally from at least one of an alkyl acrylate or methacrylate whose alkyl group has from 1 to 8 carbon atoms. The polymer composition is present in the form of a mixture of (A) a polymer of ethylene and (B) a copolymer of ethylene and an unsaturated anhydride of a dicarboxylic acid. The weight ratio (A) to (B) lies between 1 to 6 and 6 to 1.Application is to the production of articles having an improved impact resistance.
