Title (EN) POLYMER COMPOSITIONS CONTAINING OXYGEN SCAVENGING COMPOUNDS
(FR) COMPOSITIONS POLYMERES RENFERMANT DES COMPOSES ELIMINANT L'OXYGENE
Abstract:
(EN) An oxygen scavenging composition of a carrier, such as a polymer, which is permeable to both oxygen and water or water vapor and an oxygen scavenging compound of an organic compound or salt thereof dispersed relatively uniformly throughout the polymer in an amount effective to act as an oxygen scavenger. The oxygen scavenging compound may be an ascorbate compound or a polycarboxylic or salicylic acid chelate or complex of a transition metal or a salt thereof. The oxygen scavenging composition is activated for scavenging oxygen by contact with water or water vapor which permeates into or through the carrier. A catalyzing agent is included in an amount sufficient to increase the rate of oxygen scavenging by the ascorbate compound, while a reducing agent may be added to enhance the performance of the polycarboxylic or salicylic acid chelate or complex. The oxygen scavenging compound may be added to the composition in a dry state, and is inactive until activated for oxygen scavenging by contact with water or water vapor.
(FR) L'invention concerne une composition éliminant l'oxygène d'un porteur, tel qu'un polymère, qui est tout à la fois perméable à l'oxygène et à l'eau ou à la vapeur d'eau, ainsi qu'un composé éliminant l'oxygène d'un composé organique ou d'un sel de ce dernier, dispersé pratiquement uniformément dans le polymère dans une quantité efficace pour agir en tant qu'éliminateur d'oxygène. Le composé éliminateur d'oxygène peut être un composé d'ascorbate ou un chélate ou un complexe d'acide salicylique ou d'acide polycarboxylique d'un métal transitoire ou d'un sel de ce dernier. La composition éliminant l'oxygène est activée pour éliminer l'oxygène, lorsqu'elle est mise en contact avec de l'eau ou de la vapeur d'eau qui s'infiltre dans le porteur ou qui le traverse. Un agent catalyseur est prévu dans une quantité suffisante pour augmenter le taux d'élimination d'oxygène par le composé d'ascorbate, et on peut ajouter un agent réducteur pour accroître la performance du chélate ou du complexe d'acide salicylique ou d'acide polycarboxylique. On peut ajouter à la composition, le composé éliminant l'oxygène à l'état sec, ce dernier reste alors inactif aussi longtemps qu'il n'est pas activé, par contact avec de l'eau ou de la vapeur d'eau, pour éliminer l'oxygène.
