Dynamic light scattering provides a clear indication of the transition in ternary polymer blends (consisting of a diblock copolymer and two homopolymers) from a fully disordered mixture at higher temperatures to a well-developed bicontinuous microemulsion at lower temperatures. Small-angle neutron scattering allows examination of the interfaces in terms of curvature and copolymer coverage.
