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.
