Provided is a modified ethylene-vinyl alcohol copolymer, wherein the copolymer is represented by a following formula (I), contents (mol %) of a, b, and c based on the total monomer units satisfy following formulae (1) through (3), and a degree of saponification (DS) defined by a following formula (4) is not less than 90 mol %, n 18≦ a ≦55 (1)n n0.01≦ c ≦20 (2)n n[100−( a+c )]×0.9≦ b ≦[100−( a+c )] (3)n n DS =[(Total Number of Moles of Hydrogen Atoms in X, Y , and Z )/(Total Number of Moles of X, Y , and Z )]×100 (4). |
