PROCESS FOR PRODUCING ETHYLENE/VINYL ALCOHOL COPOLYMER RESIN, ETHYLENE/VINYL ALCOHOL COPOLYMER RESIN, AND MULTILAYER STRUCTURE

摘要

Provided are a method for producing an EVOH resin having sufficient long-run workability in melt molding and enabling prevention of coloring such as yellowing, an EVOH resin obtained by this method for production, and a laminate obtained from this resin. Additionally, a method for producing an ethylene-vinyl alcohol copolymer resin capable of efficiently drying while inhibiting deterioration of qualities is provided. The method for producing an ethylene-vinyl alcohol copolymer resin of the present invention includes a step of irradiation with an infrared ray for irradiating with an infrared ray an ethylene-vinyl alcohol copolymer or an ethylene-vinyl ester copolymer that is a precursor of the ethylene-vinyl alcohol copolymer.
