Abstract:
1. An oxygen-absorbing resin composition comprising (A) a hydrogenated styrene-diene copolymer comprising carbon-carbon double bonds derived from the diene in the amount of 1×10 −5 to 1×10 −2 eq/g; (B) a thermoplastic resin including ethylenic structural units in its molecular structure; and (C) a transition metal catalyst, wherein the resin (B) is a polyethylene resin, the content of which in the resin composition ranges from 90 to 99% by mass and the oxidation of the thermoplastic resin (B) proceeds while the copolymer (A) serves as a trigger and the composition thus absorbs oxygen; and wherein the resin (B) is a linear low-density polyethylene resin whose side chain consists of linear hydrocarbons in the amount of not more than 0.003 eq/g; and wherein resin (B) is free of added ethylene-vinyl alcohol copolymer (EVOH).
