对一系列高腈阻隔聚合物的吸水性进行了研究，作为聚合物组成、橡胶含量、温度、取向和相对湿度的函数。结果表明，吸水对聚合物的力学性能和热性能有很大影响。高腈聚合物中的吸收水导致玻璃化转变温度和屈服应力的大幅度降低。发现这些效应取决于聚合物组合物、吸收的水的量和取向度。这些结果的意义进行了讨论，在有关的最终使用性能的聚合物。
Water absorption studies were made on a series of high nitrile barrier polymers, as a function of polymer composition, rubber content, temperature, orientation and relative humidity. Results indicate that absorbed water has a great influence on both mechanical and thermal properties of the polymer. Absorbed water in high nitrile polymers causes a large decrease in the glass transition temperature and yield stress. These effects are found to depend on polymer composition, amount of absorbed water, and degree of orientation. The significance of these results is discussed in relation to end-use properties of the polymer.
