Abstract
Official abstract text for this publication.
An ethylene-vinyl alcohol copolymer composition is substantially free from coloration, and contains: (A) an ethylene-vinyl alcohol copolymer; (B) a polyamide resin; and (C) an iron compound; wherein the iron compound (C) is present in an amount of 0.01 to 20 ppm on a metal basis based on the weight of the ethylene-vinyl alcohol copolymer composition.
First claim
Opening claim text (preview).
The invention claimed is: 1. An ethylene-vinyl alcohol copolymer composition comprising: (A) an ethylene-vinyl alcohol copolymer; (B) a polyamide resin; and (C) an iron compound; wherein a weight ratio of the ethylene-vinyl alcohol copolymer (A) to the polyamide resin (B) is (A)/(B)=99/1 to 60/40; and wherein the iron compound (C) is present in an amount of 0.01 to 10 ppm on a metal basis based on the weight of the ethylene-vinyl alcohol copolymer composition. 2. Pellets comprising the ethylene-vinyl alcohol copolymer composition according to claim 1 . 3. A multilayer structure comprising a layer that comprises the ethylene-vinyl alcohol copolymer composition according to claim 1 .
