Electron microscopic observation of spinodal decomposition in blends of tetramethyl polycarbonate and polystyrene

Abstract The time development of spinodal decomposition in a blend of tetramethyl bisphenol-A polycarbonate with polystyrene can be followed using permanganic etching and scanning electron microscopy. This method of observation provides a real-space technique for observing the morphology of spinodal decomposition at high resolution.
