CA 2657603

The invention relates to a process for increasing the rate of oxo-biodegradation of a carbon- containing polymer which process at least comprises the step of adding a component containing at least one 1,2-oxo-hydroxy-moiety as an oxidation catalyst to the carbon-containing polymer. The invention further relates to a composition with an increased rate of oxo-biodegradability that is obtained by the process of the invention and to the product with increased rate of oxo- biodegradability made from the composition.

L'invention concerne un procédé destiné à accroître le taux d'oxo-biodégradation d'un polymère contenant du carbone, ce procédé comprenant au moins l'étape d'adjonction d'un composant contenant au moins un groupe fonctionnel 1,2-oxo-hydroxy en tant que catalyseur d'oxydation, au polymère contenant du carbone. L'invention concerne, en outre, une composition à taux accru d'oxo-biodégradabilité obtenue au moyen du procédé de l'invention et un produit à taux d'oxo-biodégradabilité accru fabriqué à partir de cette composition.
