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
Opening claim text (preview).
The invention claimed is: 1. A resin composition, comprising: (A) an ethylene-vinyl alcohol copolymer; and (B) an unsaturated aldehyde, wherein: a content of the ethylene-vinyl alcohol copolymer (A) with respect to the resin composition is 95% by mass or more; and a content of the unsaturated aldehyde (B) with respect to the resin composition 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 1 , 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, the acetic acid salt, or both, 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 comprising the resin composition according to claim 1 .
