A method for producing a saponified ethylene-vinyl acetate copolymer which comprises saponifying an ethylene-vinyl acetate copolymer in an alcohol-based solvent with an alkali catalyst, wherein an amount between 100 ppm and 15,000 ppm of water with respect to the ethylene-vinyl acetate copolymer is supplied into the alcohol-based solvent. According to this method, discoloration, etc. of a saponified ethylene-vinyl acetate copolymer is inhibited, and visual characteristics of the saponified copolymer are improved. <IMAGE> |
