Oxygen-absorbing component, oxygen absorbent package and oxygen-absorbing multilayered body containing same

摘要

There are disclosed a powdery or particulate oxygen-absorbing component excellent in oxygen-absorbing performance which can be used even in a dry state; an oxygen absorbent package; an oxygen-absorbing multilayered body each containing this oxygen-absorbing component; and a sheet-like and a film-like oxygen-absorbing multilayered body containing the same; and methods for preparing them. Specifically, the oxygen-absorbing component comprises a crosslinked polymer having carbon-carbon unsaturated bonds and is characterized by high heat resistance and easiness of grinding due to the crosslinked structure.
