OXYGEN-ABSORBING RESIN COMPOSITION

摘要

An oxygen-absorbing resin composition containing a base resin having a thermoplastic resin; and an oxygen-absorbing component having at least the one selected from the group consisting of an ester, an amide, an imide or a dicarboxylic acid derived from an acid anhydride represented by the following formula (1),;wherein,a ring X is an aliphatic ring having an unsaturated bond,n is a number of the substituents Y bonded to the ring X and is an integer of 0 or 1, andY is an alkyl group,

and a polymer having a constituent unit stemming from the acid anhydride. An oxygen-absorbing polyester resin composition exhibits excellent oxygen-absorbing property even in the absence of transition metal catalyst without accompanied by the deterioration of the polyester resin used as a the base resin, the oxygen-absorbing property being strong enough for maintaining gas-barrier properties.
