摘要： Oxygen-scavenging compositions comprising an oxidizable metal component, an electrolyte component and a solid, non-electrolytic, acidifying component. When blended with soft, flexible polymeric resins, these compositions exhibit good oxygen-scavenging performance with improved oxidation efficiency relative to compositions containing an oxidizable metal component, an electrolyte, and an acidifying component combined with a more rigid thermoplastic resins. Selection of a thermally stable non-electrolytic, acidifying component is important when melt compounding the compositions into polymeric resins and particularly for extrusion coating applications. The compositions can be used directly as an oxygen absorbent resin melt-fabricated into a wide variety of oxygen-scavenging packaging articles or as concentrates in combination with other thermoplastic resins.

摘要： Multilayered plastic bottles are disclosed having oxygen scavenging capacity sufficient to maintain substantially zero or near zero (depending on product requirements) presence of oxygen in the bottle cavity for the planned shelf life of the bottled product under specified storage conditions. The bottles feature a layer comprised of oxygen scavenger copolyester and may be used for bottling beer and other products requiring nearly total absence of oxygen for the duration of the target product shelf life.

摘要： Compositions for scavenging oxygen are disclosed. These compositions comprise condensation copolymers comprising predominantly polyester segments and an oxygen scavenging amount of polyolefin oligomer segments. The polyester segments comprise segments derived from typical bottling and packaging polyesters such as PET and PEN. The copolymers are preferably formed by transesterification during reactive extrusion and typically comprise about 0.5 to about 12 wt % of polyolefin oligomer segments. The copolycondensates are capable of absorbing at least 0.4 cc of oxygen per gram of copolymer in the solid state at ambient temperatures and are typically used as layers in films, liners, cups, wraps, bottles, etc. Use of these oxygen scavenging compositions in bottles provides a clear and rigid bottle similar in appearance to unmodified polyester bottles. In a series of preferred embodiments, bottles fabricated with the oxygen scavenging copolycondensates of this invention are over 99.4 wt % polyester and suitable for recycle with other polyester bottles.
摘要翻译：公开了用于清除氧气的组合物。这些组合物包含主要包含聚酯链段和除氧量的聚烯烃低聚物链段的缩合共聚物。聚酯片段包含衍生自典型装瓶和包装聚酯如PET和PEN的片段。共聚物优选通过反应性挤出期间的酯交换形成，并且通常包含约0.5至约12重量％的聚烯烃低聚物链段。共聚缩聚物能够在环境温度下以固体状态吸收每克共聚物至少0.4cc的氧气，并且通常用作膜，衬里，杯子，包装，瓶子等中的层。在氧气瓶中使用这些除氧组合物提供了一种与未改性聚酯瓶相似的透明刚性瓶子。在一系列优选实施方案中，用本发明的除氧共聚缩聚物制造的瓶子超过99.4重量％的聚酯并且适合于与其它聚酯瓶一起循环使用。
