Ethylene-vinyl alcohol copolymer composition and method for producing same, melt-forming material and pellets using same, and multilayer structure and production method thereof

Abstract

An ethylene-vinyl alcohol copolymer composition which suppresses thermal degradation during melt molding is provided as follows. An ethylene-vinyl alcohol copolymer composition contains: an ethylene-vinyl alcohol copolymer (A); at least one compound (B) selected from a group consisting of a metal compound belonging to period 4 d-block of along Periodic Table (other than a titanium compound) (B1), a specific polyolefin resin (B2), an olefin polymer (B3), a polyamide resin (B4), and a styrene derivative having a substituent at an α-position (B5); and a titanium compound (C), wherein the amount of the titanium compound (C) on a metal basis is 0.00005 ppm or more and less than 5 ppm per mass of the ethylene-vinyl alcohol copolymer composition.
