Abstract
A synthetic-resin laminated structure is fabricated by bonding together in a molten state a layer of a nitrile-containing polymer (I), an interposed layer of a polymer mixture (II) comprising a nitrile-containing polymer (A) and an olefin-containing polymer (B) blended together, and a layer of an olefin-containing polymer (III). The laminated structure may have more than three layers, but the layer of the polymer mixture (II) is always interposed between the layers of the polymers (I) and (III). The laminated structure may be in the form of a sheet, a tube, or a hollow article such as a bottle.
