  • 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).

  • Patent number: 8580890
    Abstract: The present invention concerns a heterophasic propylene copolymer of high melt flow for injection molding, which comprise a propylene polymer matrix and a rubber. The heterophasic propylene copolymers of the present invention are characterized by a high viscosity of the rubber phase and a well-defined ratio of the intrinsic viscosities of the rubber phase and the propylene polymer matrix, thus resulting in improved mechanical properties. The present invention further relates to a process for the production of such heterophasic propylene copolymers, their use and articles produced with them.
