The effects of the presence of dimer acid (DA) molecules in Na‐sulfonated polystyrene (PSSNa) and poly(styrene‐co Na‐methacrylate) (PSMANa) ionomers on the ionomer properties were investigated using a dynamic mechanical analysis technique. The DA decreased the matrix and cluster T g s of PSSNa ionomer without changing the ionic modulus, suggesting that the DA resided both in the matrix and cluster regions of PSSNa ionomer and acted mainly as a plasticizer. On the other hand, the DA decreased the cluster T g of PSMANa ionomer, without changing the matrix T g , and also increased the ionic modulus, implying that the DA behaved like plasticizer only for the cluster regions. © 2013 Wiley Periodicals, Inc.
