Patent number: 7709567Abstract: The present invention herein provides an oxygen-absorbing resin composition which is excellent in the oxygen-absorbability and which can inhibit any deterioration through oxidation during the molding operations of the composition and does not accordingly undergo any coloration during the molding operations. The present invention thus provides an oxygen-absorbing resin composition characterized in that it comprises (A) a hydrogenated styrene-diene copolymer; (B) a thermoplastic resin including ethylenic structural units in its molecular structure; and (C) a transition metal catalyst, wherein the oxidation of the thermoplastic resin (B) proceeds while the copolymer (A) serves as a trigger and the composition thus absorbs oxygen. In this respect, the copolymer (A) comprises carbon-carbon double bonds derived from the diene in an amount ranging from 1×10.5 to 1×10.2 eq/g.Type: GrantFiled: February 10, 2006Date of Patent: May 4, 2010Assignee: Toyo Seikan Kaisha, Ltd.Inventors: Hiroaki Goto, Ikuo Komatsu, Takayuki Ishihara, Yoshihiro Ohta, Shigenobu Murakami, Nobuo Hirakawa

Publication number: 20050142373Abstract: 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).Type: ApplicationFiled: February 23, 2005Publication date: June 30, 2005Applicant: TOYO SEIKAN KAISHA, LTD.Inventors: Ikuo Komatsu, Hiroaki Goto, Shigenobu Murakami, Takayuki Ishihara
