  • Structures with multiple polymeric layers
    Patent number: 6982106
    Abstract: Multilayer polymer structures comprising a layer (A) based on at least one halohydrocarbon polymer linked to a layer (C) based on at least one olefin polymer via a layer (B) containing from 100% to 10% by weight of at least one grafted olefin polymer and from 0 to 90% by weight of at least one halohydrocarbon polymer, the grafted olefin polymer being obtained by grafting a polymerizable monomer, a functional oligomer or a functional telomer onto a preactivated olefin polymer; process for obtaining them and use thereof.
    Type: Grant
    Filed: December 18, 2001
    Date of Patent: January 3, 2006
    Assignee: SOLVAY (Societe Anonyme)

  • Polymeric adhesive and structures with multiple polymeric layers, their process of preparation and their use
    Patent number: 6740412
    Abstract: Polymeric adhesive comprising a homogeneous mixture of at least three constituents: (a) at least one thermoplastic halogenated hydrocarbon polymer, (b) at least one copolymer of monoethylenic monomers which carry an alkyl carboxylate functional group and (c) at least one alpha-olefin polymer modified by the incorporation of at least one functional group chosen from a carboxyl, an acid anhydride, a hydroxyl and an epoxide. Process for the preparation of this polymeric adhesive and use of this polymeric adhesive in the preparation of structures with multiple polymeric layers. Structures with multiple polymeric layers comprising a layer (A) based on thermoplastic halogenated hydrocarbon polymer bonded to a layer (C) based on thermoplastic nonhalogenated polymer incompatible with (A) via a layer (B) based on this polymeric adhesive.
