METHOD FOR PRODUCING ETHYLENE-VINYL ALCOHOL COPOLYMER RESIN, ETHYLENE-VINYL ALCOHOL COPOLYMER RESIN, AND MULTILAYER STRUCTURE |
摘要 |
Provided is by the present invention is 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. The present invention is a method for producing an ethylene-vinyl alcohol copolymer resin, the method including a step of saponifying an ethylene-vinyl ester copolymer to obtain an ethylene-vinyl alcohol copolymer, in which the method is characterized by further including a step of irradiating the ethylene-vinyl ester copolymer or the ethylene-vinyl alcohol copolymer with an infrared ray. |
