Polymer blend technology is attractive from the standpoint of both science and industry, and many combinations have been studied. Recently, the polymer blends, including liquid crystalline polymer, have been especially worthy of notice, [1,2,3]. In order to obtain materials with a high mechanical strength and moldability for use in thin molded items, we chose polyamide (PA)-liquid crystalline polymer (LCP) blends. In this study, we first measured the mechanical properties, then studied the features of the polymer structure. We also examined the relationship between morphology and mechanical properties. As a result, we found that the mechanical properties of the blends depended largely on blend morphology, and that mechanical strength increased as blend compatibility increased. On the other hand, we also found that the blends showed compatible and microheterogeneous dispersion at less than 25 wt% LCP, while at more than 30 wt% LCP, blends tended to show twophase separation.
