摘要

PCT No. PCT/SE89/00388 Sec. 371 Date Jan. 8, 1991 Sec. 102(e) Date Jan. 8, 1991 PCT Filed Jul. 6, 1989 PCT Pub. No. WO90/00504 PCT Pub. Date Jan. 25, 1990.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 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 during refluxing conditions for obtaining the active component having capacity to scavenge oxygen. The polymer composition in admixture with a further polymer can be molded into containers, intermediate forms or parts thereof.
