    摘要： The present invention relates to laminated membranes formed by multilayer processing techniques including alternating layers of thermoplastic urethane and a barrier material such as a copolymer of ethylene and vinyl alcohol. The membranes are characterised in that significant hydrogen bonding occurs between the layers of thermoplastic urethane and the barrier material. The membranes are specifically characterised in that hydrogen bonds are formed between the layer including thermoplastic urethane and the layer including at least one copolymer of ethylene and vinyl alcohol.
    Products in the form of cushioning devices made from flexible membranes employing at least one layer including thermoplastic urethane and at least one layer of a copolymer of ethylene and vinyl alcohol are inflatable to a relatively high pressure. The cushioning devices maintain the internal inflatant pressure for extended periods of time by employing a phenomenon referred to in the industry as diffusion pumping. Ideally, the cushioning devices of the present invention can be permanently inflated with gases such as nitrogen or air.
    Still other products such as bladders useful for inflatable objects, such as footballs, basketballs, soccer balls and inner tubes; food packaging films; fuel liner; fuel storage tanks and pressurised accumulators, among others, are formable utilising the laminated membranes described herein.

    摘要翻译： 本发明涉及通过多层加工技术形成的层压膜，其包括热塑性聚氨酯和隔离材料的交替层，例如乙烯和乙烯醇的共聚物。 膜的特征在于，在热塑性聚氨酯和阻隔材料的层之间发生显着的氢键。 膜的特征在于，在包括热塑性聚氨酯的层和包含至少一种乙烯和乙烯醇的共聚物的层之间形成氢键。 使用由至少一层包括热塑性聚氨酯和至少一层乙烯和乙烯醇共聚物的柔性膜制成的缓冲装置形式的产品可充气至相对高的压力。 缓冲装置通过使用工业中称为扩散泵送的现象来长时间地维持内部增压压力。 理想地，本发明的缓冲装置可以用诸如氮气或空气的气体永久充气。 还有其他产品，例如用于充气物品（如足球，篮球，足球和内胎）的气囊; 食品包装膜; 燃料内衬 燃料储存罐和加压蓄能器等可利用本文所述的层压膜成形。
