OXYGEN ABSORBING RESIN COMPOSITION AND OXYGEN ABSORBING ADHESIVE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide an oxygen absorbing material that has high practicability and stably exhibits excellent oxygen absorbing performance without adding a transition metal catalyst.SOLUTION: An oxygen absorbing resin composition is provided, which comprises hydrogen peroxide and a polyester having a structural unit derived from an acid component (A). The acid component (A) has a structure selected from a group consisting of the following (i) and (ii): (i) a dicarboxylic acid or a dicarboxylic acid anhydride bonded to both of the following structures (a) and (b) and having a carbon atom bonded to one hydrogen atom, where the carbon atom is included in an alicyclic structure, and (a) is a carbon-carbon double bond group and (b) is a carbonyl group; and (ii) a dicarboxylic acid or a dicarboxylic acid anhydride in which a carbon atom adjoining to a carbon-carbon double bond in an unsaturated alicyclic structure is bonded to an electron donating substituent and a hydrogen atom, and another carbon atom adjoining to the above carbon atom is bonded to a carbonyl group, where the electron donating substituent and the carbonyl group are located at cis-positions.
