Abstract

Abstract The melt rheological behavior of chloro‐polyether and polyepichlorohydrin blends was studied. It was found that both the coupled and uncoupled blends at different blending ratios are pseudoplastic, but there was a great difference in pseudoplastic behavior between them. All the blends obeyed the principles of temperature superposition and composition superposition for plots of shear stress vs. shear rate. A model is proposed to describe and predict the rheological behavior of the blends.
