Abstract

Interfacial instability of an A/B polymer blend at the reactive interfaces where end reactive A* and B* polymers react to form A-B diblock copolymers were studied by the dynamic self-consistent field theory. The phase separation dynamics is coupled to the hydrodynamic flows of the Navier-Stokes equation. In the early stage, small vortices are generated at the interface. The result suggests that the hydrodynamic flows effectively increase the instability of the reactive interfaces.
