Document Type and Number:
Japanese Patent JP6753311
Kind Code:
B2
Abstract:
An object of the invention is to provide an EVOH which has improved melt moldability and is excellent in terms of gas barrier property and secondary formability. The present invention relates to an ethylene-vinyl alcohol copolymer that, when examined by liquid chromatography, gives an ethylene content distribution curve which has at least two peaks and in which the ethylene content (a) of a component that shows a highest peak (A), the ethylene content (b) of a component that shows a second highest peak (B), and the proportion (v) and distribution of component(s) (V) having ethylene contents (w) corresponding to specific regions (W) are within specific ranges.
