A polymer composition for manufacturing containers, intermediate forms or parts thereof for improving their oxygen barrier properties is described. According to the invention, the composition contains as an active component a metal compound having the capacity to scavenge oxygen and consisting of a metal ion having complexing properties and a polymer to which the metal ion is combined as a complex. A method of producing said polymer composition is also described, according to which a polymer is treated with a metal compound dissolved or slurried in a volatile solvent composition under refluxing conditions for obtaining the active component having the capacity to scavenge oxygen. The polymer composition in admixture with a further polymer can be molded into containers, intermediate forms or parts thereof.
