In this study, mechanical properties of nylon 6 and random poly(ethyl acrylate-co-acrylic acid) (PEAA) ionomer blends were measured. In this experiment, the PEAA content of the Nylon 6/PEAA blends were 5, 10, 20, 30 wt%. In additon, the acid groups of the copolymers were completely neutralized with LiOH and Zn(CH3CO2) to make PEAA ionomers. UTM was used to measure the mechanical properties, and the results showed that Nylon 6 blended with PEAA showed higher elongation but lower tensile strength than pure Nylon 6. Tensile strength was 30 % lower than Nylon 6 blended with PEAA than pure Nylon 6, and elongation was 2 ~ 3 times higher than that of pure Nylon 6. On the other hand, comparing the tensile strength and elongation of the Li-ionomer blends and the Zn-ionomer blends showed no difference. It was found that the mechanical properties of nylon 6 were affected by the blended content rather than the type of cations of the ionomer. |
