Claim Text:
1. A process for producing a resin composition comprising at least a thermoplastic resin and active particles that have been dispersed in the thermoplastic resin and are reactive with oxygen in an atmosphere, the process comprising: protecting the active particles with a dispersion medium to prevent oxygen in the atmosphere from contacting with the active particles; removing the dispersion medium while melt-kneading the thermoplastic resin and the active particles protected with the dispersion medium to replace the dispersion medium with the thermoplastic resin; and cooling and solidifying the thermoplastic resin with the active particles dispersed therein, wherein the active particles are formed of a metal obtained by subjecting an alloy, which comprises at least one transition metal (A) selected from the group consisting of manganese group metals, iron group metals, platinum group metals, and copper group metals and at least one additional metal (B) selected from the group consisting of aluminum, zinc, tin, lead, magnesium, and silicon, to treatment with an acidic or alkaline aqueous solution to elute and remove at least a part of the at least one additional metal (B).
