Abstract
A 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.
