In this study, mechanical properties of Nylon 11 and Na- and Li-neutralized poly(ethyl acrylate-co-acrylic acid) (PEAA) ionomer blends were measured by using UTM. The PEAA ionomer contents in the blends were 5, 10, 20 and 30 wt%. The Nylon 11/PEAA ionomer blends showed similar tensile strength values (~350 N) but 10 to 30 % lower elongation values than pure Nylon 11. On the other hand, when comparing the elongation of the Li-ionomer blends and the Na-ionomer blends, the Li-ionomer blends was found to be higher than that of Na-ionomer blends, but there was no difference in tensile strength. Thus, it can be concluded that the mechanical properties of nylon 11 were affected more strongly by the type of cations rather than the ionomer contents. |
