摘要： A gas barrier layered product and a method for producing the same are provided. The gas barrier layered product exhibits a high oxygen barrier property regardless of humidity, exhibits a high oxygen barrier property even after being subjected to retort processing, and is excellent in strength and transparency. In order to provide the gas barrier layered product, the gas barrier layered product includes a base material and a layer stacked on at least one surface of the base material. The layer is formed of a composition that includes: a hydrolyzed and condensed product of at least one compound (L) containing a metal atom to which at least one characteristic group selected from a halogen atom and an alkoxy group has been bonded; and a neutralized product of a polymer containing at least one functional group selected from a carboxyl group and a carboxylic anhydride group. At least a part of the —COO— group contained in the at least one functional group has been neutralized with metal ions having a valence of two or more.

摘要： A saponified ethylene-vinyl acetate resin, containing from 0.1 to 3000 ppm of a compound having a molecular weight of at most 1000 and having at least one conjugated double bond, an alkoxy group content of from 0.0005 to 1 mol %, an ethylene content of from 5 to 60 mol %, and a degree of saponification of at least 85 mol % has good melt extrusion stability, drawdown resistance, interlayer adhesion and gas barrier properties, and products made therefrom have good surface smoothness. The saponified ethylene-vinyl acetate resin may be produced by polymerizing a mixture of ethylene and vinyl acetate in the presence of a polymerization initiator having an alkoxy group, thereby producing an ethylene-vinyl acetate copolymer, adding a compound having a molecular weight of at most 1000 and at least one conjugated double bond to the ethylene-vinyl acetate copolymer, then saponifying the ethylene-vinyl acetate copolymer, thereby forming a saponified ethylene-vinyl acetate copolymer.
