摘要：
The present invention provides an ethylene-vinyl alcohol copolymer which can be melt-molded at lower temperatures than conventional ethylene-vinyl alcohol copolymers to give molded objects that are inhibited from suffering undesirable coloration or having fish-eyes and that have excellent gas barrier properties. The ethylene-vinyl alcohol copolymer of the invention has a carboxylic acid ester group at a polymer terminal.
