Abstract:
An oxygen-absorbing composition which comprises(a) a powdery or particulate crosslinked polymer comprising crosswise connecting points that connect parallel chains of the polymer, said crosslinked polymer having (i) an average particle diameter of 0.01 to 5 mm, (ii) 0.001 to 0.025 mol of carbon-carbon unsaturated bonds per gram, and (iii) 0.0001 to 0.02 mol of said crosswise connecting points per gram, said crosslinked polymer being a polymer formed by partially crosslinking a polymer of a diene or a copolymer of a diene and another unsaturated compound and(b) a catalyst for an oxidation reaction, said catalyst including at least one of a metal and a metallic compound.
