  The present invention relates to a polymer composition with an increased rate of oxygen-uptake by the presence of a co-catalyst and an oxidation catalyst. The oxidation catalyst has the following structure with R 1 : a group selected independently from one another from the groups consisting of H, an optionally substituted C 1 -C 20 alkyl group, an optionally substituted C 6 -C 20 aryl group, an optionally substituted C 7 -C 20 alkylaryl group, and an optionally substituted C 7 -C 20 arylalkyl group; R 2 : OR, SR, NRR′, R, O − M + ; in which R, R′: a group selected independently from one another from the groups consisting of H, an optionally substituted C 1 -C 20 alkyl group, an optionally substituted C 6 -C 20 aryl group, an optionally substituted C 7 -C 20 alkylaryl group, and an optionally substituted C 7 -C 20 arylalkyl group; M + : an alkaline metal cation or earth alkaline metal cation, or an ammonium ion; R 3 : SR, NRR′, R, O − M + ; in which R, R′: a group selected independently from one another from the groups consisting of H, an optionally substituted C 1 -C 20 alkyl group, an optionally substituted C 6 -C 2 aryl group, an optionally substituted C 7 -C 20 alkylaryl group, and an optionally substituted C 7 -C 20 arylalkyl group; M + : an alkaline metal cation or earth alkaline metal cation, or an ammonium ion. R 1 -R 3 may be joined together to form a cyclic structure. Or R 3 : OR in which R: a group selected independently from one another from the groups consisting of H, an optionally substituted C 1 -C 20 alkyl group, an optionally substituted C 6 -C 20 aryl group, an optionally substituted C 7 -C 20 alkylaryl group, and an optionally substituted C 7 -C 20 arylalkyl group and at least one of R 1 , R 2 and R 3 are joined together and form a cyclic structure containing less than 5 carbon atoms. The co-catalyst is at least one of an alkaline metal salt, earth alkaline metal salt or an ammonium salt. The invention further relates to a process to increase the rate of oxygen-uptake by a polymer composition. The invention also relates to a process to increase the oxo-biodegradability of a polymer composition and to the use of such a composition for the preparation of a product having a controlled lifetime. The invention further relates to a process to increase the rate of oxygen-scavenging in a composition containing a carbon-containing polymer, the composition obtained by this method and its use in the preparation of an oxygen-scavenging product. The present invention further relates to objects containing an oxygen scavenging layer containing such a composition.
