| Abstract |
In this work, the water absorption behavior of PSMA ionomer and PSITA ionomer was compared. In both ionomer systems, the water uptake increased with increasing ion concentration. When the ionic concentrations of the two ionomers were less than 15 mol%, the water uptake increased by about 1 wt%/(mol% of ion content). On the other hand, high ion content PSMA ionomers (> 15 mol%) showed a rapid increase of water uptake by about 2.5 wt%/(mol% of ion content). This implied that in the carboxylated polystyrene ionomers a remarkable change in physical properties took place at the ion concentration of 15 mol%. Interestingly enough, “15 mol%” coincided with the ion content, at which the ion-containing polymers were classified into either ionomers ( < 15 mol%) or polyelectrolytes (>15 mol%). |
