A new electron microscopy technique was used to observe two-phase morphology in polymer blends. It consisted of preparing a fiat specimen surface by microtoming, staining the unsaturated domains with Os04, and scanning electron microscope observation of the composition images using backscattered electrons. The new technique was applied to the melt blends of polypropylene (PP)/polybutadiene and PP/ethylene-propylene-diene rubber systems. Compared with conventional scanning electron microscope observation using secondary electron imaging for fractured surfaces, the new technique yielded a much clearer phase contrast.
