| Abstract: | Water absorption and other properties of polyamides can potentially be modified by blending with polyesters. The compatibility of a polyester ionomer melt‐blended with nylon‐6 is studied in this article, examining the effect of blending upon crystallization behaviors, morphology, thermal/mechanical properties, and water absorption. Comparisons of the crystallization behaviors of the ionomer/nylon‐6 blends with poly(ethylene terephthalate)/nylon‐6 blends suggest increased compatibility due to greater interactions between the two phases. The results indicate that the presence of a significant amount of the ionomeric groups is required to improve polyester compatibility with polyamides. © 2006 Wiley Periodicals, Inc.
