Abstract
The present invention herein provides an oxygen-absorbing resin composition which is excellent in the oxygen-absorbability and which can inhibit any deterioration through oxidation during the molding operations of the composition and does not accordingly undergo any coloration during the molding operations. The present invention thus provides an oxygen-absorbing resin composition characterized in that it comprises (A) a hydrogenated styrene-diene copolymer; (B) a thermoplastic resin including ethylenic structural units in its molecular structure; and (C) a transition metal catalyst, wherein the oxidation of the thermoplastic resin (B) proceeds while the copolymer (A) serves as a trigger and the composition thus absorbs oxygen. In this respect, the copolymer (A) comprises carbon-carbon double bonds derived from the diene in an amount ranging from 1×10.5 to 1×10.2 eq/g.
