Abstract
The present invention relates to resin pellets which comprises a thermoplastic resin (A) and an oxidation catalyst (B) which is not supported by any carrier, wherein if the peak area in the vicinity of 1715 cmis defined to be Ic and the peak area observed in the vicinity of 1470 cmis defined to be Im in the IR spectroscopic measurement of the pellets, the ratio: Ic/Im observed for the surface of the pellet is greater than that observed for the interior thereof. The pellets are thermoplastic resin pellets excellent in the oxygen-absorbing capacity and accordingly, they can suitably used as pellets for molding an oxygen absorptive resin article.
