Abstract
A high-quality oxygen-absorbing resin composition which is obtained without suffering resin scorching. Also provided are pellets for the oxygen-absorbing resin composition which comprise a thermoplastic resin (A) and an oxidation catalyst. After the pellets are mixed with a trigger resin and a thermoplastic resin (C), the trigger resin functions as a trigger to cause the oxidation of the thermoplastic resins (A) and (C) to proceed. As a result, the resultant composition absorbs oxygen.

1-16. (canceled)
A method for preventing an oxygen-absorbing resin composition from burning during melt kneading of the composition, comprising the steps of preparing a masterbatch which comprise a thermoplastic resin (A) and an oxidation catalyst and then melt kneading the masterbatch with a trigger resin and a thermoplastic resin (C), wherein the trigger resin functions as a trigger to cause the oxidation of the thermoplastic resins (A) and (C) to proceed, whereby oxygen is absorbed.
