Patent
CA 2241775
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.
La divulgation concerne : un constituant pulvérulent ou particulaire, absorbant l'oxygène avec un excellent rendement d'absorption et pouvant être utilisé même à l'état sec; un système complet pour l'absorption d'oxygène; un corps multicouche absorbant l'oxygène, chaque couche renfermant le constituant absorbant l'oxygène; un corps multicouche de type feuille ou pellicule absorbant l'oxygène, à base dudit constituant; les méthodes pour le préparer. Le constituant absorbant l'oxygène contient spécifiquement un polymère réticulé possédant des liaisons insaturées carbone-carbone, et il est caractérisé par une forte résistance thermique et une grande facilité de broyage, attribuable à la structure réticulée.
