In this study, we compared the water absorption of random poly(styrene-co-itaconate) (PSITA) ionomers and PSITA / PEG blends. The contents of PEG (average molecular weight = 4000) of the PSITA / PEG blend were 10 and 20 wt%. In this experiment, the acid groups of the copolymers were completely neutralized with NaOH and LiOH to make PSITA ionomers. The results showed that the ionomers blended with PEG absorbed more water than the pure PSITA ionomers. On the other hand, when comparing the water absorption of Li-ionomer blends and Na-ionomer blends, water absorption was increased up to 2 wt% in case of Li-ionomer blends, but up to 10 wt% in case of Na-ionomer blends. It was found that the water absorption of the blends was more than pure ionomers. It was also observed that the water absorption was affected by the blended PEG content and the type of cations of the ionomers.
