    • 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.
    • 本发明提供一种氧吸收性树脂组合物,其吸氧性优异,并且能够抑制组合物成型时的氧化劣化,并且在成型操作中不会发生任何着色。 因此,本发明提供了一种吸氧树脂组合物,其特征在于它包含(A)氢化苯乙烯 - 二烯共聚物; (B)其分子结构中含有乙烯结构单元的热塑性树脂; 和(C)过渡金属催化剂,其中当共聚物(A)用作触发剂时,热塑性树脂(B)的氧化进行,并且组合物因此吸收氧气。 在这方面,共聚物(A)包含衍生自二烯的碳 - 碳双键,其量为1×10 5〜1×10 2 eq / g。
