Abstract: A multilayer film is provided that includes a) a barrier layer including a thermoplastic polyester elastomer or a polyamide copolymer; b) an intermediate layer provided on the barrier layer and including a maleic anhydride (MAH)-grafted polyolefin and an a-olefin copolymer; and c) an adhesive layer provided on the intermediate layer and including a thermoplastic polyester elastomer or a polyamide copolymer. The multilayer film enables production of gas-tight multilayer laminates which exhibit an excellent peel resistance combined with a low weight and/or thickness. Further, a multilayer laminate and an inflatable airbag that include a fabric layer adhered to the multilayer film, as well as methods of manufacturing are described.

Abstract: A multilayer film, which is used upon being adhered to a fabric, includes an adhesive layer to be a side of the multilayer film to be adhered to the fabric; and a barrier layer bonded to the adhesive layer. Each of the adhesive layer and the barrier layer includes a thermoplastic polyester elastomer. A melting point of the barrier layer is higher than a melting point of the adhesive layer. A ratio value of a content ratio of a soft segment in the thermoplastic polyester elastomer in the adhesive layer with respect to a content ratio of a soft segment in the thermoplastic polyester elastomer in the barrier layer, is 5 or less.

Abstract: A multilayer film is provided that includes a barrier layer, and an adhesive layer, which includes a maleic anhydride (MAH)-grafted polyolefin. The barrier layer has a melting point higher than the adhesive layer, and the melting point of the barrier layer is higher than 165° C. The multilayer film enables production of gas-tight multilayer laminates which exhibit a high peel resistance combined with a low weight and/or thickness. Further, a multilayer laminate and an inflatable airbag that include a fabric layer adhered to the multilayer film, as well as a method of its manufacturing are described.

Abstract: The present invention provides a method for producing a porous membrane. The method allows: avoidance of use of a solvent that places a large load on the environment; relatively easy control of parameters such as the porosity and the pore diameter; and high chemical stability of a resultant porous membrane. The method for producing a porous membrane of the present invention includes the steps of: preparing an epoxy resin composition containing an epoxy resin, a curing agent represented by H2N—(CH2)n—NH2 where n is an integer from 4 to 8, and a porogen; forming a cured product of the epoxy resin composition into a sheet shape or curing a sheet-shaped formed body of the epoxy resin composition, so as to obtain an epoxy resin sheet; and removing the porogen from the epoxy resin sheet by means of a halogen-free solvent.
