Patent

CA 2488485

An oxygen absorption resin composition is provided that comprises a thermoplastic resin (A) having carbon-carbon double bonds substantially in its main chain and a transition metal salt (B). If necessary, the composition further comprises a gas barrier resin (C), a compatibilizer (D) and the like. The composition has excellent oxygen absorption properties, and when the composition is employed, generation of odorous substances derived from the decomposition of resins as a result of oxygen absorption can be suppressed.

Composition de résine d'absorption d'oxygène qui comprend une résine thermoplastique (A) ayant des liaisons doubles carbone-carbone sensiblement dans sa chaîne principale et un sel de métal de transition (B). Au besoin, la composition comprend également une résine de barrière contre les gaz (C), un agent de compatibilité (D) et analogue. La composition présente d'excellentes propriétés d'absorption d'oxygène si bien qu'elle permet d'éliminer la production de substances odorantes dérivées de la décomposition des résines.
