| titleOfInvention | Composition with a polymer and an oxidation-catalyst |
| abstract | 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 R1 : a group selected independentl y from one another from the groups consisting of H, an optionally substituted C1-C2O alkyl group, an optionally substituted C6- C20 aryl group, an optionally substituted C7-C20 alkylaryl group, and an optionally substituted C7-C20 arylalkyl group; R2: 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 C1-C20 alkyl group, an optionally substituted C6-C20 aryl group, an optionally substituted C7-C20 alkylaryl group, and an optionally substituted C7-C20 arylalkyl group; M+: an alkaline metal cation or earth alkaline metal cation, or an ammonium ion; R3: 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 C1-C20 alkyl group, an optionally substituted C6-C20 aryl group, an optionally substituted C7-C20 alkylaryl group, and an optionally substituted C7-C20 arylalkyl group; M+: an alkaline metal cation or earth alkaline metal cation, or an ammonium ion. R1-R3 may be joined together to form a cyclic structure. Or R3: OR in which R: a group selected independently from one another from the groups consisting of H, an optionally substituted C1-C20 alkyl group, an optionally substituted C6-C20 aryl group, an optionally substituted C7-C20 alkylaryl group, and an optionally substituted C7-C20 arylalkyl group and at least one of R1, R2 and R3 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. |
