The present invention relates to a preparation method for an ethylene-vinyl alcohol copolymer, with which it is possible to obtain ethylene-vinyl alcohol copolymers having a high saponification rate, whilst minimizing the amount of alkali catalyst that is used. La présente invention concerne un procédé de préparation d'un copolymère éthylène alcool de vinyle, avec lequel il est possible d'obtenir des copolymères éthylène-alcool de vinyle ayant un taux de saponification élevé, tout en réduisant au minimum la quantité de catalyseur alcalin qui est utilisé. 본 발명은 알칼리 촉매의 사용량을 최소화하면서 높은 비누화도의 에틸렌-비닐알코올 공중합체를 수득할 수 있는 에틸렌-비닐알코올 공중합체의 제조방법에 관한 것이다.
