  • Thermoplastic elastomer polyblends comprising polyamides/modified polyolefins and shaped articles produced therefrom
    Patent number: 5616418
    Abstract: Polyblend compositions well adopted for the production of a wide variety of useful shaped articles having improved physical/chemical properties, e.g., fibers, films, sheets, composites, and the like, comprise (a) at least one polyamide thermoplastic elastomer, e.g., a polyetheresteramide, and (b) at least one modified polyolefin, e.g, an optionally maleized copolymerizate of ethylene and vinyl acetate, a copolymerizate of ethylene and (meth)acrylic acid, a copolymerizate of ethylene, vinyl acetate and (meth)acrylic acid and/or an alkyl (meth)acrylate, a copolymerizate of ethylene, an alkyl (meth)acrylate and, optionally, maleic anhydride, or maleized SBS, SIS or SEBS.

  • Adhesive film composition
    Patent number: 5506310
    Abstract: A thermoplastic film, adapted for adhesion, composed of a compound of polyamide-based thermoplastic elastomers and of copolymers of olefins, the latter preferably being constituted of at least two different monomers of olefins. The composition of the thermoplastic film is such that the thermoplastic elastomers represent at least 50% and preferably 60% of the total weight of the compound.
    Type: Grant
    Filed: June 8, 1994
    Date of Patent: April 9, 1996
    Assignee: Elf Atochem S.A.
    Inventors: Thierry Vasselin, Michel Vuachet, Gilles Recher
  • Ski structure obtained from a polyamide based thermoplastic elastomer and grafted copolyolefin based film adapted for adhesion
    Patent number: 5348804
    Abstract: The invention relates to adhesion of various elements of a structure, such as a ski, consisting of an assembly of at least one first element and a second element by the action of an adhesive layer made of resin or foam, by interspersing at least one thermoplastic film, adapted for adhesion, and composed of a compound of polyamide-based thermoplastic elastomers and of copolymers of olefins, the latter preferably being constituted of at least two different monomers of olefins, between the adhesive layer and the junction surface of the first element. The composition of the thermoplastic film is such that the thermoplastic elastomers represent at least 50% and preferably 60% of the total weight of the compound.

  • Snow ski soles
    Patent number: 5069976
    Abstract: Improved snow ski and other soles (bases), having enhanced and durable wax absorption, are fabricated from a sheet or film of a thermoplastic polymeric material based on an intimate admixture of one or more polyolefins, e.g., high density polyethylene, and one or more polyetheresteramides.
