    Abstract: Compositions comprising a polymer having less than 5 aliphatic carbon-carbon double bonds per 100 copolymerized monomer units, an oxidizable metal, and a compound selected from the group consisting of ferrous salts having an anion selected from the group consisting of ascorbate, nitrate, citrate, gluconate, lactate and mixtures thereof are effective oxygen-scavenging compositions. The compositions are suitable for use as components of food and pharmaceutical packaging materials. In addition, compositions consisting essentially of a polymer having a less than 5 aliphatic carbon-carbon double bonds per 100 copolymerized monomer units, an oxidizable metal and a ferrous sulfate salt exhibit rapid uptake of oxygen in compositions substantially free of electrolytes having halide anions.

    Abstract translation: 包含每100个共聚单体单元具有少于5个脂族碳 - 碳双键的聚合物的组合物,可氧化金属和选自以下的化合物:选自抗坏血酸盐,硝酸盐,柠檬酸盐, 葡萄糖酸盐,乳酸盐及其混合物是有效的氧清除组合物。 该组合物适合用作食品和药物包装材料的组分。 此外,基本上由每100个共聚单体单元具有小于5个脂肪族碳 - 碳双键的聚合物组成的组合物,可氧化金属和硫酸亚铁盐显示出基本上不含具有卤化物阴离子的电解质的组合物中的氧气的快速吸收。
