摘要：

The reduction of O2 transport due to the presence of trace amounts of moisture correlates with the suppression of the dielectric gamma-relaxation in the amorphous nylon 6-I/T(70/30). This relaxation corresponds to motions involving the aliphatic regions of the polymer. Water molecules alter the interaction between amides on neighboring chain segments. Low moisture levels reduce the mobility of aliphatic chain segments and thus reduce oxygen transport through these regions.
