ABSTRACT:
The invention aims at providing an oxygen-absorbing resin which has excellent oxygen absorption performance and which can dispense with the addition of a transition metal catalyst or the irradiation with a radiation. The invention provides an oxygen-absorbing resin which is obtained by polymerizing a raw material containing a monomer (A) having an unsaturated alicyclic structure bearing a carbon-carbon double bond wherein one carbon atom adjacent to the carbon-carbon double bond is bonded to an electron-donating substituent and a hydrogen atom and another carbon atom adjacent to the carbon atom is bonded to a heteroatom-containing functional group or a bonding group derived from the functional group with the electron-donating substituent and the functional or bonding group taking cis-configuration and which contains the unsaturated alicyclic structure in an amount of 0.5 to 10 meq/g; oxygen-absorbing resin compositions containing the above oxygen-absorbing resin; and oxygen-absorbing containers, characterized by having an oxygen-absorbing layer made from the resin or the compositions.
