摘要：
Polybenzimidazole (PBI) is known to absorb 15 wt% water at equilibrium. This sorbed water greatly affects the mechanical properties of this polymer. Both FTi.r. and broadline n.m.r. have been used to study the interaction between water and PBI. The results clearly show that the water in PBI is mobile and therefore does not hydrogen bond to the polymer chain.
