Abstract
Official abstract text for this publication.
The present invention provides a resin composition containing (A) an ethylene-vinyl alcohol copolymer and (B) an unsaturated aldehyde (B), in which the content of the unsaturated aldehyde (B) with respect to the resin composition containing the ethylene-vinyl alcohol copolymer is 0.01 ppm or more and 100 ppm or less. The unsaturated aldehyde (B) is preferably crotonaldehyde, 2,4-hexadienal, 2,4,6-octatrienal or a combination thereof. In addition, it is preferred that the resin composition further contains a boron compound, and the content of the boron compound is 100 ppm or more and 5,000 ppm or less. Also, it is preferred that the resin composition further contains a conjugated polyene compound, and the content of the conjugated polyene compound is 0.01 ppm or more and 1,000 ppm or less.
First claim

1 . A resin composition, comprising: (A) an ethylene-vinyl alcohol copolymer; and (B) an unsaturated aldehyde, wherein a content of the unsaturated aldehyde (B) with respect to the resin composition comprising the ethylene-vinyl alcohol copolymer is 0.01 ppm or more and 100 ppm or less. 2 . The resin composition according to claim 1 , wherein the unsaturated aldehyde (B) is (B-1) an unsaturated aliphatic aldehyde. 3 . The resin composition according to claim 2 , wherein the unsaturated aldehyde (B) is crotonaldehyde, 2,4-hexadienal, 2,4,6-octatrienal or a combination thereof. 4 . The resin composition according to claim 1 , further comprising a boron compound, wherein a content of the boron compound is 100 ppm or more and 5,000 ppm or less. 5 . The resin composition according to claim 1 , further comprising a conjugated polyene compound, wherein a content of the conjugated polyene compound is 0.01 ppm or more and 1,000 ppm or less. 6 . The resin composition according to claim 5 , wherein the conjugated polyene compound is sorbic acid, a sorbic acid salt or a combination thereof. 7 . The resin composition according to claim 1 , further comprising acetic acid, an acetic acid salt, or both, wherein a content of acetic acid and the acetic acid salt is 50 ppm or more and 1,000 ppm or less. 8 . The resin composition according to claim 1 , further comprising a phosphorus compound, wherein a content of the phosphorus compound is 1 ppm or more and 200 ppm or less. 9 . A multilayered structure comprising at least one or more layers each constituted with the resin composition according to claim 1 .
