ETHYLENE-VINYL ALCOHOL COPOLYMER COMPOSITION, PELLET, MULTILAYER STRUCTURE, METHOD FOR PRODUCING ETHYLENE-VINYL ALCOHOL COPOLYMER COMPOSITION, AND METHOD FOR PRODUCING MULTILAYER STRUCTURE

Document Type and Number:

Japanese Patent JP2023152992

Kind Code:

A

Abstract:

To provide an ethylene-vinyl alcohol copolymer composition which is suppressed in coloring change due to thermal deterioration during melt molding.SOLUTION: An ethylene-vinyl alcohol copolymer composition contains an ethylene-vinyl alcohol copolymer, a boron compound, and a titanium compound. The content of the titanium compound in terms of metal is 0.001 ppm or more and less than 5 ppm per mass of the ethylene-vinyl alcohol copolymer composition.SELECTED DRAWING: None
