Title (EN) OXYGEN-ABSORBING MATERIAL AND MOLDED OBJECT OBTAINED THEREFROM
(FR) MATERIAU ABSORBANT L'OXYGENE ET OBJET MOULE A PARTIR DE CE MATERIAU
Abstract: front page image
(EN)An oxygen-absorbing material which comprises a transition metal compound and one or more thermoplastic resins. When used as a molding such as a container, the oxygen-absorbing material not only absorbs oxygen from the contents but cuts off oxygen due to its excellent gas-barrier and oxygen-absorbing properties. It can hence keep the contents in an oxygen-free state over long. High oxygen absorption is attained, e.g., by using as at least one of the thermoplastic resins a resin having an amino group content of 20 mmol/kg or lower or by reducing the crystallizability of the thermoplastic resin(s).
(FR)L'invention concerne un matériau absorbant l'oxygène qui comprend un composé métallique de transition et au moins une résine thermoplastique. Utilisé pour un moulage tel qu'un contenant, ledit matériau non seulement absorbe l'oxygène du contenu, mais le bloque aussi du fait de ses excellentes propriétés de perméabilité au gaz et d'absorption d'oxygène. Il permet donc de conserver longtemps le contenu dans un état exempt d'oxygène. On obtient une absorption d'oxygène élevée en utilisant, par exemple, au moins une résine thermoplastique dont la teneur en groupe aminé n'excède pas 20 mmol/kg, ou en réduisant la capacité de cristallisation de la(des) résine(s) thermoplastique(s).
