摘要

Composition of oxygen absorption resin comprising a polyester compound and a transition metal catalyst, wherein the polyester compound has at least one constituent unit having a tetral ring selected from the group consisting of the constituent units represented by the following general formulas (1) to (4): ** Formula ** in which R each independently represents a monovalent substituent, the monovalent substituent being at least one selected from the group consisting of a halogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heterocyclic group, a cyano group, a hydroxyl group, a carboxyl group, an ester group, an amido group, a nitro group, an alkoxy group, a group aryloxy, an acyl group, an amino group, a mercapto group, an alkylthio group, an arylthio group, a heterocyclic thio group and an imido group, which may also have a substitution go; in which m each independently represents an integer from 0 to 3; in which n each independently represents an integer from 0 to 6, and at least one hydrogen atom is attached to a benzyl position of the tetralin ring; wherein X each independently represents a divalent group containing at least one group selected from the group consisting of an aromatic hydrocarbon group, a saturated or unsaturated alicyclic hydrocarbon group, a saturated or unsaturated, linear or branched aliphatic hydrocarbon group, and a heterocyclic group, wherein the transition metal catalyst comprises at least one transition metal selected from the group consisting of manganese, iron, cobalt, nickel and copper.
