  • Oxygen-absorbing resin composition and laminate
    Patent number: 8592522
    Abstract: The object of the present invention is to provide an oxygen-absorbing resin composition having a high oxygen absorbability and capable of absorbing oxygen for a long period of time. The present invention provides an oxygen-absorbing resin composition comprising polyolefin resin (A) obtained by polymerizing an olefin having 2 to 8 carbon atoms, resin (B) which is other than resin (A) and which acts as a trigger for the oxidation of resin (A), and transition metal catalyst (C), wherein resin (B) is dispersed in the matrix of resin (A) so that the oxidation reaction of matrix resin (A) is caused and thus oxygen is absorbed when the oxygen-absorbing resin composition is brought into contact with oxygen. This oxygen absorbing resin composition has a high oxygen absorbability and is advantageous in cost because oxygen is absorbed in resin (A).
