Abstract
The authors study the effect of excess neutralizing agent on the fatigue properties of sulfonated ionomers. Second, they study the ion content effect on fatigue properties of ionomer samples obtained by steam stripping method, which does not add any excess amount of NaOH. Finally, the change in fatigue performance will be discussed in terms of ionic aggregate structure (multiplet-cluster). It is found that fatigue performance decreases with increasing ion content up to 5 mol %. This is attributed to the crosslinking effect of small ionic aggregates (multiplets). The fatigue lifetime increases sharply at ca. 5 mol %, which corresponds to the critical ion content of polystyrene-based ionomers. This increase in fatigue performance is related to the dominant role of large ionic aggregates (clusters).
