Abstract
The present invention relates to a polymer composition with an increased rate of oxygen-uptake by the presence of an oxidation catalyst. 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.
