Abstract
A method for producing an ethylene-vinyl alcohol copolymer resin composition, wherein an ethylene-vinyl alcohol copolymer resin is contacted with an aqueous solution containing both carbon dioxide gas and at least one additive selected from the group consisting of an alkali metal salt (A) and a boron compound (B). The present invention can provide an environmentally friendly method for producing an EVOH resin composition, the method releasing no carboxylic acid such as acetic acid to the ambient atmosphere. In addition, the invention can provide an EVOH resin composition which emits less smell and is superior also in long-run workability.
