    摘要: Disclosed is a multilayered structure that includes no less than 8 resin-layers, the resin-layer including a layer A constituted with a resin composition containing a gas barrier resin, and a layer B constituted with a resin composition containing a thermoplastic resin, at least one of the resin compositions included in the layer A and the layer B that are adjacent with each other containing a metal salt, the content of the metal salt being no less than 1 ppm and no greater than 10,000 ppm in terms of metal element equivalent, and an interlayer adhesive force between the layer A and the layer B being no less than 450 g/15 mm. The layer A and the layer B may be alternately laminated. Moreover, the average thickness of single layer of at least one selected from the layer A and the layer B is preferably no less than 0.01 μm and no greater than 10 μm.

    摘要: Provided is a modified ethylene-vinyl alcohol copolymer (C) having an ethylen content of 5 to 55 mol %, which contains a specific structural unit (I) in an amount of 0.3 to 40 mol % and may be obtained by reacting an ethylene-vinyl alcohol copolymer (A) with a monofunctional epoxy compound (B) having a molecular weight of not more than 500. This can be produced by a method for producing the modified ethylene-vinyl alcohol copolymer (C) which comprises melting and kneading an ethylene-vinyl alcohol copolymer (A) with a monofunctional epoxy compound (B) in an extruder. The modified ethylene-vinyl alcohol copolymer (C) is superior to a unmodified ethylene-vinyl alcohol copolymer (A) in transparency, stretchability, flexibility and flexing resistance due to the specific structural unit (I) incorporated therein, and thus, can be used as a barrier material in various applications requiring the above performance capabilities.

    摘要: Disclosed is an innerliner for pneumatic tires, wherein the innerliner comprises a modified ethylene-vinyl alcohol copolymer (C) obtained by reacting 1-50 parts by weight of an epoxy compound (B) with 100 parts by weight of an ethylene-vinyl alcohol copolymer (A) having an ethylene content of 25-50 mol %. A pneumatic tire with the innerliner can greatly improve the internal pressure retainabilities before and after driving without increasing the weight of the tire.
