Abstract
An oxygen absorption resin composition is provided that comprises a thermoplastic resin (A) having carbon-carbon double bonds substantially in its main chain and a transition metal salt (B). If necessary, the composition further comprises a gas barrier resin (C), a compatibilizer (D) and the like. The composition has excellent oxygen absorption properties, and when the composition is employed, generation of odorous substances derived from the decomposition of resins as a result of oxygen absorption can be suppressed.
Claims17
An oxygen absorption resin composition comprising a thermoplastic resin (A) having carbon-carbon double bonds substantially in its main chain, a transition metal salt (B), and a gas barrier resin (C),
- wherein the thermoplastic resin (A) satisfies the following inequality (1):
- 100×b/(a+b)≦X (1)
- wherein a (mol/g) is an amount of carbon carbon double bonds in its main chain, b (mol/g) is an amount of carbon-carbon double bonds in its side chain, and X is 10, and
- wherein the gas barrier resin (C) is a polyvinyl alcohol resin having an oxygen transmission rate of 20 ml·20 μm/(m2·day·atm) or less in 65% RH at 20° C.;
- wherein the thermoplastic resin (A) is polybutadiene.
