Jr.Attorney, Agent or FirmInternational ClassB32B 27/08 (20060101)AbstractA synthetic resin laminated structure is produced by bonding together in a molten state a layer of a (I) nitrile barrier resin, (II) a layer of a polymer mixture comprising a nitrile barrier resin and a halogenated polyolefin, and (III) a layer of a thermoplastic resin. The thermoplastic resins useful in this invention include polyolefins such as polyethylene and polypropylene, polyvinylchlorides, styrene containing polymers such as ABS, SAN and polystyrene, polycarbonates, polyurethanes, polysulfones, polyamides and nitrile barrier resins.Field of SearchEster, halide or nitrile of addition polymerPolyene monomer-containing Ester, halide or nitrile of addition polymer Of polycarbonate Of polythioether Next to second layer of polyamidoester Next to addition polymer of ethylenically unsaturated monomer Next to second addition polymer from unsaturated monomers Monoolefin polymer Next to vinyl or vinylidene chloride polymer Polymer of monoethylenically unsaturated hydrocarbon Ester monomer type (polyvinylacetate, etc.) Halide monomer type (polyvinyl chloride, etc.) | |
