Abstract

Blends of poly(ethylene oxide) and polystyrene were analyzed using scanning electron microscopy with image analysis and rheological measurements to determine the region of cocontinuity. Local maxima in the amount of interface in the blends and in the elastic modulus at low frequency correspond to the boundaries of the region of cocontinuity. Annealing of the samples caused some blends near the boundaries of the region of cocontinuity to break up into dispersed morphologies, while other blends remained cocontinuous, despite dramatic increases in the size scale.
