Polymer blends with dynamic asymmetry have attracted much interest recently. In this study, we report a more typical case where the dynamically asymmetric system is highly immiscible we find that there is a transient network growth and phase inversion for the slow minor component The network structure shows a hierarchical growth behavior, which is the result of competition between a slow relaxation-controlled concentration growth an local scale and a fast hydrodynamic growth on large scale: When phase separation couples with a subsequent crystallization, the interfacial boundary may assist lateral crystallization and irregular spherulites would grow epitaxially around the amorphous :component-morphological control in material processing.
