The present invention relates to a modified ethylene-vinyl alcohol-based copolymer, a method for preparing same, and a molded article comprising same. Specifically, in one embodiment of the present invention, provided is a modified ethylene-vinyl alcohol-based copolymer comprising: an ethylene-derived repeating unit; a second repeating unit derived from vinyl alcohol; and a third repeating unit derived from tetraethyl orthosilicate (TEOS). La présente invention concerne un copolymère à base d'éthylène-alcool vinylique modifié, son procédé de préparation et un article moulé le comprenant. Plus particulièrement, dans un mode de réalisation, la présente invention concerne un copolymère à base d'éthylène-alcool vinylique modifié comprenant : une unité de répétition issue de l'éthylène ; une deuxième unité de répétition dérivée de l'alcool vinylique ; et une troisième unité de répétition dérivée de l'orthosilicate de tétraéthyle (TEOS). 본 발명은 변성 에틸렌-비닐알코올계 공중합체, 이의 제조 방법 및 이를 포함하는 성형품에 관한 것이다. 구체적으로, 본 발명의 일 구현예에서는, 에틸렌 유래 반복단위; 비닐알코올 유래 제2 반복단위; 및 테트라에틸 오르토실리케이트(Tetraethyl orthosilicate, TEOS) 유래 제3 반복단위를 포함하는, 변성 에틸렌-비닐알코올계 공중합체를 제공한다.
