    摘要: The present invention provides methods for producing an ethylene-vinyl acetate copolymer and a saponified product thereof, in which defective appearances at the time of molding (e.g. fish eye or coloring) can be inhibited while using a recovered solvent. In the present invention, a recovered alcohol-based solvent is supplied for reuse after decreasing the concentration of an aldehyde compound contained in the solvent. The concentration of an aldehyde compound can be decreased by acetalizing it with an acid such as a cation exchange resin. For example, the concentration of an aldehyde compound in the solvent is not more than 100 ppm, and the concentration of an acetal compound in the solvent is at least 0.1 ppm but not more than 10,000 ppm.
