PROBLEM TO BE SOLVED: To provide an active oxygen barrier material having sufficient oxygen scavenging property and barrier property to provide an oxygen sensitive products having a storage life of 6 months to 2 years. SOLUTION: The active oxygen scavenging property-imparted copolymer has polyaddition segment and an oxygen scavenging portion segment selected from a group consisting of polypropylene, poly(4-methyl)-1-pentene, polybutadiene, polypropylene oxide oligomer, methyl pendant aromatic compounds and their mixtures. And an oxygen barrier laminate comprising a layer of the active oxygen scavenging property-imparted copolymer and a layer of a packaging material is provided. COPYRIGHT: (C)2004,JPO&NCIPI
