Mapping the phase diagram of an aromatic polyamide blend using infrared spectroscopy

Abstract

Abstract The results of an infrared study of poly ( meta ‐phenylene adipamide)‐poly (ethylene oxide) blends are reported. This is the first time, to the authors' knowledge, that infrared spectroscopy has been used to experimentally map the phase diagram of a polymer blend. The results are compared with theoretical phase diagrams calculated from a recently described association model.
