  Provided is a modified ethylene-vinyl alcohol copolymer (C) having an ethylen content of 5 to 55 mol %, which contains a specific structural unit (I) in an amount of 0.3 to 40 mol % and may be obtained by reacting an ethylene-vinyl alcohol copolymer (A) with a monofunctional epoxy compound (B) having a molecular weight of not more than 500. This can be produced by a method for producing the modified ethylene-vinyl alcohol copolymer (C) which comprises melting and kneading an ethylene-vinyl alcohol copolymer (A) with a monofunctional epoxy compound (B) in an extruder. The modified ethylene-vinyl alcohol copolymer (C) is superior to a unmodified ethylene-vinyl alcohol copolymer (A) in transparency, stretchability, flexibility and flexing resistance due to the specific structural unit (I) incorporated therein, and thus, can be used as a barrier material in various applications requiring the above performance capabilities.

  提供的是一种改性乙烯-醋酸乙烯共聚物(C)，其乙烯含量为5至55摩尔％，其中含有一种特定的结构单元(I)，其含量为0.3至40摩尔％，可通过将乙烯-醋酸乙烯共聚物(A)与分子量不超过500的单官能环氧化合物(B)反应而获得。该改性乙烯-醋酸乙烯共聚物(C)的制备方法包括在挤出机中熔融和揉捏乙烯-醋酸乙烯共聚物(A)与单官能环氧化合物(B)。由于其中包含了特定的结构单元(I)，改性乙烯-醋酸乙烯共聚物(C)在透明度、可伸展性、柔韧性和耐弯曲性方面优于未改性的乙烯-醋酸乙烯共聚物(A)，因此可以用作在需要上述性能能力的各种应用中的障壁材料。
