According to the present invention, an ethylene-vinyl alcohol copolymer having a novel structure, and a method of producing the same are provided. A method of producing an ethylene-vinyl alcohol copolymer with respect to the present invention is the one using an 1,4-polybutadiene as a raw material, wherein the 1,4-polybutadiene is hydroborated in a solvent, followed by oxidation to be hydroxylated, characterized in that the hydroboration is carried out in a condition in which the solution of the 1,4- polybutadiene is in non-gel state.
L'invention concerne un copolymère d'alcool éthylénique/vinylique présentant une nouvelle structure, ainsi qu'un procédé de production de ce copolymère. Ce procédé de production d'un copolymère d'alcool éthylénique/vinylique consiste à réaliser l'hydroboration de 1,4-polybutadiène utilisé comme matière de départ dans un solvant, puis à oxyder le produit d'hydroboration en vue de réaliser une hydroxylation. Ledit procédé se caractérise en ce que la solution est maintenue dans un état non gélifié pendant l'hydroboration.
