Oxygen-absorbing resin composition, not responsive to a metal detector, producing no odor after absorption of oxygen and has excellent oxygen-absorbing performance in a wide range of humidity conditions from low to high humidity. An oxygen-absorbing molded article, and a multilayer body, container, injection-molded article and medical containers also provided. The oxygen absorbing resin composition contains a polyester, comprising at least one constituent unit having a tetralin ring component compound, a transition metal catalyst, and a catalyst for producing the polyester. The oxygen-absorbing molded article of the present invention can be formed by molding the oxygen-absorbing resin composition into a film or a sheet. The multilayer body, container, injection-molded article, medical container, etc. of the present invention are obtained by using the oxygen-absorbing resin composition.
吸氧树脂组合物,对金属探测器无反应,吸氧后不产生气味,在从低湿度到高湿度的广泛湿度条件下具有优异的吸氧性能。此外,还提供了一种吸氧模塑制品以及多层主体、容器、注塑制品和医疗容器。吸氧树脂组合物包含一种聚酯,其中至少一个组成单元具有四萘环组分化合物、一种过渡金属催化剂和一种用于生产聚酯的催化剂。本发明的吸氧模压制品可通过将吸氧树脂组合物模压成薄膜或片材而形成。本发明的多层体、容器、注塑制品、医用容器等都是通过使用本发明的吸氧树脂组合物获得的。
