摘要：
A structure comprising one or more layers of a polymer (A) comprising: the units (A1) and the units (A2) wherein the A2/(A1+A2) molar ratio is between 0 and 30%, is suitable as a barrier against oxygen permeation under high relative humidity. The structure is, thus, useful as packaging and as hollow bodies, such as pipes, bottles and containers.
